SOLUTIONS:
1.let the 2nd discount be Rs.x.
ATQ,
1440 ×
=864
=864
x = 25%
2.Let CP = 100,MP=140,SP = 126
Actual profit = 126 - 100 = 26
% profit = 26/100 × 100 = 26%
3.Let the CP=100,MP=150
ATQ,150 × 85/100× 85/100=108.375
% profit = 8.375%
4.MP = 100
SP = 80 - 10 = 70
CP=70 × 100/120= 58.33
5.SP = 361,MP = 361×100/95= 380
CP = 380 ×100/152 = 250
6.Let actual cost price be Rs.100
Cost price of man =100 ×85/100= 85
SP of man=100 × 115/100= 115
% Profit =30/85 ×100 = 35 5/17%
7.Let CP of on item be = Rs.100
Total quantity of item = 100
Then total CP = 100 × 100 = 10000
SP of items which sold at 25% gain = 80 ×125 = 10000
SP of items which sold at MP =20 × 120 = 2400
Profit percentage =
2400/10000 × 100 = 24%
8.Let amount invested in scheme be = x
ATQ,
x=2000
Amount invested by Khushi = 2000 + 4000 = 6000
9.As given in the question 37.5%=3/8
part is sold.so remaining part is =5/8
x = 50
So initial quantity of mixture 5 × 50 = 250 ℓ
