Find the value of y in the following

1 (2/3) ÷ (2/7) x (y/7) = 1 (1/4) x (2/3) ÷ (1/6)

A 0.006

B 1/6

C 0.6

D 6

Solution

Correct Answer: Option D

1 (2/3) ÷ (2/7) x (y/7) = 1 (1/4) x (2/3) ÷ (1/6)

ধরি, 
(5/3) ÷ (2/7) x (y/7) = (5/4) x (2/3) ÷ (1/6)

⇒ (5/3) x (7/2) x (y/7) = (5/4) x (2/3) x 6

⇒ (5/6) y = 5

⇒ y = {(5 x 6)/5}

∴ y = 6
