Question

X and Y contribute ₹10 and ₹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 $=10:20=1:2$

$\therefore$ 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 = $\frac{15}{3}=5$

$\therefore$ X receives 1 part = 5 chocolates
$\therefore$ Y receives 2 parts = 10 chocolates
