Answer 2

$\bold {\huge {Solutions :-}}$


SP = Rs 3320

Let the CP be x

Gain = 1/6 of x


$\bold {\underline {A/q}}$

1/6 of x + x = 3320

=> x/6 + x = 3320

=> (x + 6x) /6 = 3320

=> 7x/6 = 3320

=> x = 3320×6/7

=> x = 2845.71


$\bold {\underline {Now, }}$

CP = x = Rs 2845.71

Gain = 1/6 of x = 1/6 × 2845.71 = Rs 474. 28


$\bold {\underline {Hence, }}$

Gain % = gain/CP × 100 %
= 474.28/2845.71 × 100 %
$\bold {= 16.66}$ % ans.
