If 35% of a number is 12 less than 50% of that number, then the number is:

A 40

B 50

C 60

D 80

Solution

Correct Answer: Option D

35% of a number is = 35*X/100

50% of the number is = 50*X/100

Now,

A.Q

50*X/100 - 35*X/100 = 12

or, (50*X - 35*X)/100 = 12

or, 15*X / 100 = 12

or, X = 12* 100/ 15

or, X = 80
