Question

how to solve 11th question

Answer 1

CP of cooler= Rs. 1600
Overhead= Rs. 900
Total CP= Rs. (1600+900)
= Rs. 2500
SP= Rs. 2000
Here, SP<CP
Then, Loss= CP-SP
= Rs. (2500-2000)
= Rs. 500
And, Loss%=
$( \frac{loss}{cp} \times 100)\%$
$(\frac{500}{2500} \times 100)\%$
$20\%$

Answer 2

Cost Price of cooler=1600+900=2500
Selling Price of cooler=2000

loss=2500-2000=500
loss% = 20%
