Question

If 15% of 40 is greater than 25% of a number by 2, then the number is
(1) 14
(2) 16
(3) 18
(4) 20​

Answer 1

Answer:

Let the no be x

So,

15% of 40 - 25% of x = 2

6 - 25x/100 = 2

-25x/100 = 2-6

-x/4 = - 4

-x = - 4 * 4

-× = - 16

X = 16

Therefore, x is 16

Answer 2

Answer:

2] 16 correct option

Step-by-step explanation:

Let the number be X. Then  

15/100 x 40 -25/100 x X=2

3/20 x 40-1/4 x X=2

6-X/4=2

24 - X /4=2

24 - X= 8

X = 16
