Question

39. Ten articles were bought for Rs.
8, and sold at 8 for
Rs. 10. The gain percent is
(1) 54.75% (2) 57.25%
(3) 56.25% (4) 55%​

Answer 1

Answer:

(3)    56.25%

Step-by-step explanation:

Cost price of 10 articles       = ₹ 8

Selling price of 8 articles     =  ₹ 10

Selling price of 10 articles    =  10 * 10/8  =  ₹ 12.5

Profit  = Selling price - Cost price  =    ₹12.5 - ₹ 8  =  ₹ 4.5

Profit % = Profit * 100 / Cost price

             =  4.5 * 100 / 8

             =  56.25 %

Answer 2

Answer :-

Option (3) 56.25 %

Explanation :-

Cost price of 10 articles (CP) = Rs. 8

Cost price of 1 article = 8/10 = Rs. 0.8

Selling price of 8 articles = Rs. 10

Selling price of 1 article (SP)10/8 = 5/4 = Rs. 1.25

Here SP > CP

So it is a gain

Gain = SP - CP

= 1.25 - 0.8

= 0.45

i.e Profit = Rs. 0.45

Profit % = (Gain/CP) * 100

= (0.45/0.8) * 100

= (45/0.8)

= 450/8

= 56.25

i.e Gain % = 56.25 %.

∴ Gain percent is 56.25 % option (3).
