1.  A person sold a table at a gain of 15%. Had he bought it for 25% less and sold it for ₹ 60 less, he would have made a profit of 32%. The cost price of table was:
A. ₹ 300
B. ₹ 350
C. ₹ 375
D. ₹ 400

Answer: Option C

Explanation:

Let the cost price of table = ₹ N

Then, selling price with 15% gain

= (100 + Gain%) x CP/100

= (100 + 15)% x CP/100

= (115 x N)/100 = ₹ 115N/100

Now CP = [(100 - 25%) x CP] / 100 = ₹75N/100

New SP = ₹ (115N/100) - 60

Now, according to the question,

[[(115/100 ) - 60) - (75N/100)] / (75N/100)] x 100 = 32

 [[(115N - 6000 - 75N)/100 ] / (75N/100)] x 100 = 32

 [(40N - 6000)/75N] x 100 =32

 (40N - 6000)/(3N x 4) = 32

 160N - 24000 = 96N

 160N - 96N = 24000

 64N = 24000

 N = 24000/64

 N = ₹375

 The cost price of table is ₹ 375.
