SOLUTION:

Explanation:
5% of 2000=100 so 2000-100=1900 so,if he sells 1900 he will get
25% profit
cost per piece rs 25……so 25x 1900 don’t solve here
if 125%…………………..25×1900
100 %………………….?
?= 25x1900x100/125=38000=CP
if 50% rejected,only 1000 pieces sold
so 1000×25=25000=SP

loss=cp-sp= 38000-25000=13000

Explanation – Let the labeled price be Rs. x
88% of 80% of x = 704
=> x = (704 x 100 x 100/88 x 80)= 1000.

Explanation – S.P after 1st discount,
100%………2000
80%………?
?=2000×80/100=1600
Net S.P = Rs. 1400.
Discount on Rs. 1600 = Rs. 200.
∴Required discount = (200/1600 x 100)% =12.5%

4.Answer – C. Rs 80, Rs 40
Explanation – Let the costs of the two articles be x and y. Then,
25% of x = 50% of y
=> x/y = 50/25 = 2/1
So,x and y must be in the ratio of 2:1

Explanation – Let the list price be Rs. x
80/100x = 40
=> x = 40 x 100/80 = 50
∴ Required S.P. = 70% of Rs. 50=Rs.35

Explanation – Let the labelled price be Rs.x Then,
(80% of x)- (70% of x) = 500
10% of x =500
10%………..500
100%…………? ?= (500 x 100/10) = 5000=x

Explanation – Let the second discount rate be x% Then,
(100 – x)% of 90% of 720 = 550.80
=> (100 – x)/100 x 90/100 x 720 = 550.80
= (100-x) = [55080/(9 x 72) = 85
=> x= 15
second discount rate =15%

Explanation – loss=2% so,
98%………….3400
100%………..?
?=(3400×100)/98=3469.34
