Chain Rule Q27

27. 8.If the price of 6 toys is Rs. 264.37, what will be the approximate price of 5 toys?

[A] Rs. 140

[C] Rs. 200

[E] Rs. 240

[B] Rs. 100

[D] Rs. 220

Answer : D

Explanation :

Let the required price be Rs. x. Then, Less toys, Less cost (Direct Proportion)

6 : 5 :: 264.37 : x

6x = (5 x 264.37)

x = (5 x 264.37) 6

x = 220.308

Approximate price of 5 toys = Rs. 220.
