Answer 1

Answer:

10. (a) 38853 (b) 250803 (c) 360 rooms (d) 328 (e) 888

Explanation:

(a) To find this we would add 25524 and 13329. So,

13329+25524 = 38853. For checking, if the answer is subtracted from any two numbers and the result is the other number then our sum is right. So,

38853-13329 = 25524. So our calculation is correct.

(b) To find this we would first find the sum of 35,294 and 85,505. So,

35294 + 85505 = 120799.

Then we would subtract the sum from 200592. So,

200592 - 120799 = 79793.

(c)  A building has 15 floors. Each floor has 8 flats. So the number of flats is

= 15 multiplied by 8 = 120. So there are total 120 flats in the building.

Each flat has 3 rooms. So the number of rooms is= 120 multiplied by 3=360

So the total number of rooms is 360 in the building.

(d) To find this we would divide 78720 by 240. So, 78720 divided by 240= 328. Answer is 328. For checking if 240 multiplied by 328 comes 78720 then our answer is correct.

(e) Before starting this question, we would first know that,

Divisor  X Quotient + Remainder = Dividend.

To find this we would first put the numbers in the formula given above. So,

25 X 35 + 13 = Dividend

Or 875 + 13 = Dividend                                            ( We multiplied 25 and 35 )

Or 888 = Dividend

Or it is our answer.
