6. Two gallons of a mixture of spirit and water contains 12% of water. They are added to 3 gallons of another mixture, containing 7% of water, again half of a gallon of water is added to the whole mixture. Find percentage of water in the resulting mixture.
17(3/11)%
11(3/10)%
15(2/121%
12(3/7)%
10(3/13)%
Option A
Required percentage of water
= (12/100 × 2 + 7/100 × 3 + 0.5)/ 5.5 × 100
= 95/5.5 = 190/11 = 17(3/11)%

7. A man bought 80 eggs at the rate of 24 rupees per dozen 10 eggs got broken and the remaining eggs he sold at 3.20 rupees per egg. If he had spent 16 rupees on other expenses, find his profit or loss percentage.
20(1/11)%
25(3/10)%
22(3/11)%
27(5/13)%
27(3/11)%
Option E
Total CP of eggs = 80 × 2 + 16 = 176 rupees
Total S.P. of remaining eggs = 70 × 3.20 = 224 rupees
Profit/loss percentage = (224−176)/176 × 100
= 4800/176 = 27(3/11)%

Rs. 1750
Rs. 1770
Rs. 1150
Option C
Total interest = Rs. 6125 Rate = 6% and increasing by 0.5% every year.
Let total Loan Amount = P P = (6125 × 100)/(6 × 1 + 6.5 × 1 + 7 × 1 + 7.5 × 1 + 8 × 1)
= 612500/35
= Rs. 1750

Option A
Let he bought 4x kg, 5x kg and 6x kg of dry fruits.
Total cost price for dealer = (4x×100) + (5x×80) + (6x×60)
= 400x + 400x + 360x = 1160x
Total selling price for dealer = 1740x
Required price per kg = 1740x/15x = 116

Option
Total = 3+4+5 = 12
n(s) = 12c3 = 220
n(e) = 3c1 * 4c1 * 5c1 = 60
P = 60/220 = 3/11
