Question

Ram distributed 50 chocolates. He gave one-fifth of the chocolates to Rahul and three-tenths of the chocolates to Vivek. How many chocolates are left with Ram?

Answer 1

Total number of chocolates = 50

Chocolates given to Rahul = One-fifth of total chocolates
$\begin{array}{cc}\frac{1}{5}\text{of}50& =\frac{1}{5}\times 50\\ & =50÷5\\ & =10\end{array}$

Chocolates given to Vivek = Three-tenths of total chocolates
$\begin{array}{cc}\frac{3}{10}\text{of}50& =\frac{3}{10}\times 50\\ & =150÷10\\ & =15\end{array}$

Total chocolates given to Rahul and Vivek = 10 + 15
= 25

Chocolates left with Ram = 50 - 25
= 25

Thus, 25 chocolates are left with Ram.
