4.Required ratio = (100 × 100) : (99 × 99.5) = 20000 : 19701

 5.No comparison can be drawn between Maurice and the others because their relative speeds cannot be determined.

6.(LCM of 30,35,15)=210
Assume total work =210 units
Rohan one day work=(210/30)= 7 units
Mohan one day work= (210/35)= 6 units
Work done by Rohan and Mohan in 15 days= (7+6)*15= 195
Work done by Rakesh= 210-195= 15 units
Share of Rakesh= (15/210)*1260= Rs 90

7.Let the rate of interest be x
So,
= 25000*6*3/100 + 12000*8*3/100 + 18000*x*3/100= 15000
= 4500 + 2880 + 540x/100= 15000
= 54000x/100= 7620
= x=14.11%

8.In the first variety of 40 liters
Milk= 40*3/7= 12 liters
Water = 40*7/10= 28 liters.
Let 5x liters of mixture from the 2nd pot be poured in into the first pot
Milk= 4x, water= x
So,
12+4x/28+x= 2/3
36+12x= 56 + 2x
10x= 20
x= 2
So, required amount of mixture to be poured= 5*2= 10 liters.

9.Required difference = [(5 – 2)/(2+3+5)] × 21000= (3/10) × 21000 = Rs.6300
