Two-fifth of one-third of three-seventh of a number is 15. What is 40 percent of that number?
Solution
Correct Answer: Option D
let the number be x
(2/5) × (1/3) × (3/7) x = 15
⇒ x = (15 × 35)/2
40% of x = {(15 × 35)/2 } × .4
= {(15 × 35)/2} × (4/10)
= 105
(2/5) × (1/3) × (3/7) x = 15
⇒ x = (15 × 35)/2
40% of x = {(15 × 35)/2 } × .4
= {(15 × 35)/2} × (4/10)
= 105
