A man purchased some eggs at $3$ for $Rs.\, 5$ and sold them at $5$ for $Rs.\, 12 .$ Thus, he gained $Rs.\, 143$ in all. The number of eggs he bought is

A

$210$

B

$200$

C

$195$

D

$190$

Solution

Let, the number of eggs bought by him be $15$ Therefore,

$C.P.$ of $15$ eggs $=₹ 25$

So, $S.P.$ of $15$ eggs $=₹ 36$

Hence, gain $=36-25=₹ 11$

Thus, $15$ eggs $=₹ 11$

$=\frac{15}{11} \times 143$

$=195\, eggs$
