- If the profit percent got on selling an article is numerically equal to its cost price and the selling price is Rs. 39, then cost price will be
Rs 25Rs 32Rs 30Rs 28NoneOption C

Solution:

SP = Rs. 39.

Let CP = x

Profit% = CP

[(39-x)/x]*100 = x

3900-100x = x2

x2+100-3900 = 0

x = Rs30.

- Kumar purchased 120 reams of paper at Rs 80 per ream. He spent Rs 280 on transportation, paid tax at the rate of 40 paise per ream and paid Rs 72 to the coolie. If he wants to have a gain of 8 %, what must be the selling price per ream?
Rs 60Rs 85Rs 90Rs 78NoneOption C

SP of 120 reams = 108% of Rs. 10000

= Rs. 10800.

SP per ream = Rs. [10800/120] = Rs. 90.
