Question

2) A man sold a horse at a loss of 7 %. Had he been able to sell it at again of 9 %, it
would have fetched Rs. 64 more than it did. What was the cost price ?
a) Rs.600 b) Rs.700 c) Rs.500 d) Rs.400​

Answer 1

Answer:

Option d : 400

Step-by-step explanation:

Let cp=x

Loss=7%

Sp=x-(7/100)x=93/100x

In 2nd case, gain=9%

Sp=x+(9/100)x=109/100x

:109/100x - 93/100x =64

:(109-93)x/100=64

:16x=64*100

:16x=6400

:x=6400/16=400

Answer 2

Answer:

400

Step-by-step explanation:

There is a short cut for this...

There is a loss of 7% ...And if man is able to sell for 9% profit then there he will get 64 Rs. more.

So,

9%x -(-7%x) = 64

(9% + 7%)x = 64

16/100 X = 64

X = 6400/16 = 400
