Answers:
1.Answer c
Selling price = 440*70/100= 308
Cost price = 308/110*100= Rs 280
- Answer b
By using M1D1H1=M2D2H2
64*50/1/2= 20(50+x)/1/2
By solving
X= 110 men.
- Answer a
Total Balls = 15 Probability = 6c3 / 15c3 = 4/91
- Answer b
Profit for 5 days = 4000*7=28000
Profit for 3 days= 6000 *3= Rs 18000
Profit for 2 days= 7500* 2= Rs 15000
Average loss in last 2 days= (33000-28000)/2= Rs 2500
- Answer c
Total work to be done in units= 120
Animesh 1 day work= 5 units
Mohit day work= 4 units
Three person 1 day work = 10 units
So,
Ronit 1 day work = 10-(4+5)=1 units
Remaining work= 120-(9*12) = 12
Ronit will do the remaining work= 12/1 = 12 days
- Answer d

- Answer c
Ratio of efficiency of a man to that of a woman= 3/5:1/3= 9:5
So, 36*x*9=48(x+7)*5
By solving, x=20 days
- Answer b
Total work= 36*20= 720 man days or 48 *27= 1296 women days
Remaining work after 6 days= 1- 6(10/720+18/1296)
= 1- 6(1/72+1/72)= 1-6*2/72= 5/6
Using MDH
20*20*1= 12*D2*5/6
D2= 40 days
