Question

Which of the following is the equation for the statements "a number increased by 11 is type the number?
​

Answer 1

Answer:

Let the required number be x.

So, five times the number will be 5x.

∴ 5x = 40

(ii) Let the required number be x.

So, when it is increased by 8, we get x + 8.

∴ x + 8 = 15

(iii) Let the required number be x.

So, when 25 exceeds the number, we get 25 - x.

∴ 25 - x = 7
