Question

X and Y contribute Rs 10 and Rs 20 respectively to buy 15 chocolates. How many chocolates should Y receive to ensure fair distribution?

• A.
  15 chocolates
• B.
  7 chocolates
• C.
  10 chocolates
• D.
  5 chocolates

Answer 1

The correct option is C

10 chocolates
The ratio in which X and Y contribute money is 10 : 20
$\Rightarrow$ 1 : 2

$\therefore$ They should receive chocolates in the ratio 1 : 2

Sum of terms of the ratio = 1 + 2 = 3
$\Rightarrow$ Value of 3 parts = 15 chocolates
$\Rightarrow$ Value of 1 part = $\frac{15}{3}=5$

$\therefore$ A receives 1 part = 5 chocolates
$\therefore$ B receives 2 parts = 10 chocolates
