Question

please give 5 me my answers

Answer 1

1) case 1 when there is a profit of 10%

SP = 1980

since its profit SP will be greater and CP will be 90% of SP

So, CP = 100 / (100+profit%) * 100

= 100/110 * 1980

= 1800

Case 2 when he suffered a loss of 10%

Loss = 10%

Sp = 1980

CP = 100 / (100-loss%) * SP

= 100/90 * 1980

= 2200

Total SP = 1980 + 1980 = 3960

Total CP = 2200 + 1800 = 4000

CP is greater hence loss

Loss = CP - SP

= 4000 - 3960 = 40

Loss % = loss/CP * 100

= 40/4000 * 100 = 1%

Answer 2

1st , 10% of 1980 = 198, +198-198 = 0 therefore net profit or loss is 0

2nd , 14 % of 1140 = 159.6 , 5%of 1140 = 57 , net profit = 159.6-57 = 102.6

x/100*(1140 *2) = 102.6 = 4.5 % profit in total
