10. A shopkeeper bought 30kg of wheat at the rate of Rs45 per kg. He sold 40% of the total quantity at the rate of Rs50 per kg. Approximately, at what price per kg should he sell the remaining quantity to make a profit of 25% overall?
(1) Rs 54
(2) Rs 52
(3) Rs 50
(4) Rs 60

1. (4)
Let C's share be Rs x.
Then, B gets =0.75 x.
A gets = 1.25×0.75x
x+0.75x+0.9375x=731
2.6875x=731
x=731⁄2.6875 =272

2. (1)
SP=Rs15000
SP after 10% discount= 15000-10%of15000
= 15000-1500=Rs13500
Profit on SP= 8%
CP= 13500⁄108 ×100=Rs 12500

3. (3)
CI=10000[{(11⁄10 )×(11⁄10 )×(11⁄10 )×(11⁄10 )}-1]

4. (4)
If the average is increased by 3 kg, then sum of weights
increases by 3 x 4 = 12 kg .
And this increase in weight is due to the extra weight included
due to the inclusion of new person.
Weight of new man = 120 + 12 = 132 kg.

5. (2)
(B+C)'s 1 day work= 1⁄8 ...(i)
(A+B)'s 1 day's work= 1⁄12 ...(ii)
(A+C)'s 1 day's work = 1⁄16 ...(iii)
On adding all these three equations,
2(A+B+C)'s one day's work = 1⁄8 +1⁄12 1⁄16 = (6+4+3)⁄48 =13⁄48
(A+B+C)'s one day's work= 13⁄96
∴A, B and C can complete the work in 96⁄13 =7 5⁄13

6. (3)
Speed of the tractor= distance/ time
=575⁄23 =25kmph
∴speed of bus= 50kmph
∴speed of car= 9⁄5 ×50=90kmph
∴distance covered by the car in 4 hours= 4×90=360km

7. (4)
Work done by the leak in 1 hour = (1⁄2 -3⁄7) = 1⁄14
∴leak will empty the tank in 14 hours.

8. (4)
CP of mixture = (20*2+30*3)⁄2+3 =26
SP of the mixture = 1.1×26=28.6

9.(4)
Let the present ages of Anju and Sandhya be 13x and 17x years
respectively.
∴13x-4⁄17x-4 =11⁄15
=>187x-44=195x-60
=>195x-187x=60-40
=>x=2
∴Required ratio= (13×2+6):(17×2+6)
=4:5

10. (4)
CP of wheat= 30×45=Rs1350
40% of 30kg =12kg
SP of 12kg = 12×50 = Rs 600
For 25% profit, total SP of all the wheat is 1350×125⁄100
=Rs 1687.5
Remaining wheat (30-12) = 18kg Rate of remaining wheat = 1087.5⁄18 ≈Rs60
