Question 31.

In an election, the successful candidate was registered 5,77,500 votes, and his nearest rival had secured 3,48,700 votes. By what total margin did the successful candidate win the election?

Number of the votes secured by the successful candidate = 5,77,500

Number of the votes secured by his nearest rival = 3,48,700

Therefore, margin of the votes is necessary to win the election = 5,77,500 – 3,48,700 = 2,28,800

Question 32.

Kirti bookstore sold books worth a total of ₹2,85,891 in the 1st week of June and books  worth a total of ₹4,00,768 in the second week of the month. How much was the total sale for the two weeks together? And in which week was the total sale greater and by how much?

Books sold in the first week of the month June are worth ₹2,85,891

Books sold in the second week of the month are worth ₹4,00,768

Therefore, the total sale of the books in the two weeks together is

= ₹2,85,891 + ₹4,00,768 = ₹6,86,659

In the 2nd week of the month, the sale of total books was greater.

Therefore, the difference in the sale of books

= ₹4,00,768 – ₹2,85,891 = ₹1,14,877

So, in the second week of June, the total sale of books was more than ₹1,14,877.

Question 33.

Find the difference below between the highest and the lowest numbers that is written using the digits 6, 2, 7, 4, and 3, each only once.

Given digits = 6, 2, 7, 4, 3

Greatest number is = 76432

Least number is = 23467

Therefore, difference = 76432 – 23467 = 52,965

Question 34.

A machine, on average, manufactures 2,825 screws a day. How many screws did it produce in January 2006?

The number of screws that are manufactured in a day = 2,825.

Number of screws that are manufactured in month of January = 31 x 2825 = 87,575

Question 35.

The total distance between the school and the house of a student is 1 km and 875 m. Every day she walks both the ways. Find the total distance she covered in six days.

Distance between the school and her house = 1 km 875 m = (1000 + 875) m = 1875 metre.

Total Distance travelled by the student from school to home and from home to school is = 2 x 1875 = 3750 m

Distance travelled by the student in six days is = 3750 m x 6 – 22500 m = 22 km 500 m.

Therefore, the total distance covered in 6 days = 22 km 500 m.

Question 36.

A merchant had ₹78,592 with her. She placed an order to purchase 40 radio sets at ₹1200 each. How much total money will remain with her after the purchase?

Amount of money present with the merchant = ₹78,592

Total Number of the radio sets = 40

Price of one of the radio set = ₹1200

Therefore, the cost of 40 radio sets = ₹1200 x 40 = ₹48,000

Remaining money left with the merchant = ₹78,592 – ₹48000 = ₹30,592

Hence, the amount of ₹30,592 will remain with her after purchasing the following radio sets.

Question 37.

A vessel has four litres and 500 ml of curd. How many total glasses, each of 25 mL capacity, can be filled?

Quantity of the curd in a vessel = 4 l 500 mL = (4 x 1000 + 500) mL = 4500 mL.

Capacity of 1 glass = 25 mL

Therefore the number of glasses = 4500/25

Question 38.

A student has multiplied the number 7236 by 65 instead of multiplying by 56. Calculate by how much was his answer greater than the right answer?

The student had multiplied the number 7236 by 65 instead of multiplying by 56.

The difference between the two above multiplications is = (65 – 56) x 7236 = 9 x 7236 = 65124

(We don’t have to do both the multiplication)

Hence, the answer that is greater than the correct answer is 65,124.

Question 39.

Estimate each of the following given numbers using the general rule:

(i) 730 + 998

(ii) 796 – 314

(iii) 12,904 + 2,888

(iv) 28,292 – 21,496

Rounding off 730 nearest to hundreds = 700

Rounding off 998 nearest to hundreds = 1,000

∴ 730 + 998 = 700 + 1000 = 1700

Rounding off 796 nearest to hundreds = 800

Rounding off 314 nearest to hundreds = 300

∴ 796 – 314 = 800 – 300 = 500

Rounding off 12,904 nearest to thousands = 13000

Rounding off 2888 nearest to thousands = 3000

∴ 12,904 + 2,888 = 13000 + 3000 = 16000

Rounding off 28,292 nearest to thousands = 28,000

Rounding off 21,496 nearest to thousands = 21,000

∴ 28,292 – 21,496 = 28,000 – 21,000 = 7,000

Question 40.

Estimate the following given products using the general rule:

(i) 578 x 161

(ii)5281 x 3491

(iii) 1291 x 592

(iv) 9250 x 29

(i) 578 x 161 = 600 x 200 = 1,20,000

(ii) 5281 x 3491 = 5000 x 3000 = 1,50,00,000

(iii) 1291 x 592 = 1300 x 600 = 7,80,000

(iv) 9250 x 29 = 9000 x 30 = 2,70,000

Question 41.

Which of the following is not true?

(i) (7 + 8) + 9 = 7 + (8 + 9)

(ii) (7 × 8) × 9 = 7 × (8 × 9)

(iii) 7 + 8 × 9 = (7 + 8) × (7 + 9)

(iv) 7 × (8 + 9) = (7 × 8) + (7 × 9)

(iii) : 7 + 8 × 9 = 7 + 72 = 79,

(7 + 8) × (7 + 9) = 15 × 16 = 240

and 79 ≠ 240

Question 42.

(iii) : 7254 * 98 is divisible by the number 22 only if it is divisible by both 2 and 11.

Given that the number is even. Therefore it is divisible by the number 2.

7254 * 98 is divisible by 11, only if

(7 + 5 + * + 8) – (2 + 4 + 9) or (20 + *) – 15 or 5 + * is also divisible by 11.

∴ The digit at * place should be filled by 6.

Question 56.

The greatest number which will always divide the product of the predecessor and successor of an odd natural number other than 1, is

(ii): As the odd natural numbers other than 1 are – 3, 5, 7, 9 and so on.

Now, we know that the predecessor and successor of 3 are – 2 and 4 respectively, and their product is two × four = 8

Similarly, we know that the predecessor and the successor of 5 are – 4 and 6, respectively, and their product is four × 6 = 24.

Thus, the above shows that the greatest number which always divides the product of the predecessor and the successor of an odd natural number other than 1 is 4.

Question 59.

A person had only ₹ 1000000 with him. He purchased a coloured-T.V. for ₹ 16580, a motorcycle for ₹ 45890 and a flat for ₹ 870000. How much money was left with him?

The total amount a person had was = ₹ 1000000

The total amount he spent on a colour T.V. was = ₹ 16580

The amount he spent on a motorcycle was = ₹ 45890

The amount he spent on a flat was = ₹ 870000

∴ Total amount he spent is = ₹ (16580 + 45890 + 870000) = ₹ 932470

Thus, the total amount left with him = ₹ 1000000 – ₹ 932470 = ₹ 67530

Question 60.

Out of 180000 tablets of Vitamin A, a total of 18734 are distributed among the students in the district. Find the total number of remaining vitamin tablets.

Total tablets of Vitamin A are = 180000

Total number of tablets distributed among the students in the district = 18734

∴ The number of total remaining vitamin tablets = 180000 – 18734 = 161266

Question 61.

Chinmay only had ₹ 610000. He gave a total of ₹ 87500 to Jyoti, ₹ 126380 to Javed and ₹ 350000 to John. How much money was left with him?

Chinmay had a total amount = of ₹ 610000

The total amount he gave to Jyoti = ₹ 87500

The total amount he gave to Javed = ₹ 126380

The total amount he gave to John = ₹ 350009

Total amount given by Chinmay is = ₹ (87500 + 126380 + 350000) = ₹ 563880

Thus, the amount left with him

= ₹ 610000 – ₹ 563880 = ₹ 46120
