Ruchika bought a book at a cost of Rs. 400. She sold it at 30% loss to Manisha. Manisha sold it to Lata at a profit of 20%. What was S.P. of Manisha? Correct Answer 336
Given:
Ruchika’s C.P. = Rs. 400
Ruchika’s Loss% = 30%
Manisha’s Profit% = 20%
Formula used:
(i) Cost price × (100 + Profit%)/100 = Selling price
(ii) Cost price × (100 - Loss%)/100 = Selling price
Calculations:
C.P. of Ruchika × (100 ‐ Loss%)/100 × (100 + profit%)/100 = S.P. of Manisha
⇒ 400 × 70/100 × 120/100 = S.P. of Manisha = Rs. 336
∴ SP of Manisha was Rs. 336.
