Show Answer Report Discussion in forumAnswer : 3) Rs 24
Solution : Cost Price of 5 kg = Rs.(14 * 2 + x * 3) = (28 + 3x).
Sell price of 5 kg = Rs. (22 x 5) = Rs. 110.
(110 - (28 + 3x)/(28 + 3x)) * 100 = 82 - 3x/28 + 3x = 1 / 10
820 - 30x = 28 + 3x
=> 33x = 792
=> x = 24

( 6 ) The ratio of cost price of two articles was 2:3, by selling getting the gain 10% and 20% then what is the percentage of gain
- 1) 16%
- 2) 12%
- 3) 6%
- 4) 30%
-
Show Answer Report Discussion in forumAnswer : 1) 16%
Solution : 2 : 3 = 2x : 3x
10 % of 2x = 10/100 * 2x = x/5
20 % of 3x = 20/100 * 3x = 3x/5
x/5 + 3x/5 = (x + 3x)/5
=> 4x/5
= (4x/5)/5x * 100 = 4x/25x * 100 = 16%
Short cut method:
2 : 3
200 : 300
in 200 = 10% ---> 20
in 300 = 20% ---> 60
20 + 60 = 80 % gain
= 80/500 * 100 = 16%
