Answer 1

10. SP = 368
loss= 8% on CP
SP = CP x 92% (loss of 8% on 100% of CP)
368 = CP x 92/100
36800 = CP x 92
CP= 36800/92 = 400
gain = 10% = 40
SP = 440

11. CP= 1500
repair = 575
total cp = 2075
SP = 2075 x 104% (gain of 4% on cp)
SP = 2075 x 104/100 = 2158
OR
2075 + 4% of 2075
= 2075 + 83 = 2158

12. CP of 3 sacks = 1500 x 3 = 4500
transportation cost = 125
total CP = 4625
SP = 5087.50
i) profit = 5087.50 - 4625 = 462.50
ii) profit % = profit/cp x 100
462.50/ 4625 x 100 = 10%

13. CP = 22000
profit = 8%
SP = 22000 x 108% = 23760

14. SP = 4000
loss = 20% on CP
SP = 80% of CP
4000 = 80% of CP
CP = 400000/80 = 5000

15. 1 crate = 10 eggs.
40 crates = 400 eggs
CP of 400 eggs = 400
25 eggs break.
CP of 375 eggs = 400
SP of 1 egg = 1.20
SP of 375 eggs = 375 x 1.20 = 450
i) profit = 450 - 400 = 50 rs
ii) profit % = 50/400 x 100 = 12.5%
