Question

A box contains $500$ oranges. Out of which $\frac{3}{25}$ are rotten and $\frac{1}{5}$ are kept for some guests. How many oranges are left in the box?

• A. $140$
• B. $350$
• C. $200$
• D. $340$

Answer 1

The correct option is D $340$

Given,

Number of oranges in a box $=500$

Rotten oranges out of $500=\frac{3}{25}$

Oranges kept for guests out of $500=\frac{1}{5}$

Number of rotten oranges $=\frac{3}{25}\text{of}500$

$=\frac{3}{25}\times 500$

$=60$

Number of oranges kept for guests $=\frac{1}{5}\text{of}500$

$=\frac{1}{5}\times 500$

$=100$

Number of oranges left in the box $=500-60-100=340$

Hence, $340$ oranges are left in the box.
