AMDOCS Profit and Loss Problems with Solutions Quiz-1

Let the cost price of the watch be x.
It was sold for 10% loss that is 90x/100

If it was sold for 140 more, the price would be 90x/100 + 140 and this would be 4% gain which is 104x/100

So, 104x/100 = 90x/100 + 140
Multiply through by 100, we have
104x =90x + 14000
Subtract 90x from both sides, we have
14x = 14000
Divide both sides by 14, we have
x = 1000
So, the cost price is 1000

CP = SP + 1CP = SP - g
800 + x = 980 - 2x
3x = 180 => x = 60
CP = 800 + 60 = 860

CP + CP/8 = 45000
CP = 40000
SP = 40000*(95/100) = 38000

10 CP = 12 SP
12 --- 2 CP loss
100 --- ? => 16 2/3%

80% --- 12
120% --- ?
80/120 * 12 = 8

SP = CP + g
50 SP = 50 CP + 15 SP
35 SP = 50 CP
35 --- 15 CP gain
100 --- ? => 42 6/7%

800*(25/100) = 200 ---- 5
? ---- 1 => Rs.40

CP = 47.50
SP = 47.50*(125/100) = 59.375
MP*(95/100) = 59.375
MP = 62.5

The total number of mangoes bought by the shopkeeper be 12.
If he buys 4 a rupee, his CP = 3
He selling at 3 a rupee, his SP = 4
Profit = SP - CP = 4 - 3 = 1
Profit Percent = 1/3 * 100 = 33 1/3 %
