SOLUTIONS:
1.
Let initially he had 5x+3x = 8x litres of
milk.
New ratio after removal of 160 liter mixture
and addition of 35 liter pure water is.
[5x-100] : [3x-60 +35] = [5x-100] : [3x-25] =
5 : 4
Solving ⇒ x = 55. So, Original quantity of
mixture = 8x = 440 liters

4.
Ratio of the equivalent capitals of
P, Q and R for 1 month = 11 × 36 : 16.5 ×
36 : 8.25 × 36
= 4 : 6 : 3
R’s share in the prfit =[ 3/(4+6+3) ]×19.5
lakh=Rs. 4.5 lakh
50% of Rs. 4.5 lakh=Rs. 2.25 lakh
5.









6.
Total number of analyst in Explatory and
Descriptive = (16 + 20)% of 3500
= 36% of 3500 = 1260
Total number of females in Explatory and
Descriptive
= (12 + 18)% of 1500 = 30% of 1500 = 450
Total number of males = 1260 – 450 = 810
Report Solution

7.
Number of males enrolled in Predictive = Total
analyst enrolled in Predictive – Total females
enrolled in Predictive
= 22% of 3500 – 11% of 1500 = 770 – 165 =
605
Number of females enrolled in Mechanistics =
38% of 1500 = 570
Req. Ratio = 570 : 605 = 114 : 121
Report Solution

8.
Total number of females enrolled in
Predictive and inferential = (11 + 21)% of
1500
= 32% of 1500 = 480
Total analysts in Mechanistics and
Descriptive
= (30 + 20)% of 3500 = 1750
Req. %=480/1750 * 100=27% aprox

9.
New Number of Explatory analyst = 20% of
11% of 1500 + 16% of 3500
= 33 + 560 = 593

10.
otal number of males in Mechanistics,
Predictive and Inferential
= Total analysts – Females analyst
= (30 + 22 + 12)% of 3500 – ( 38 + 11 +
21)% of 1500 = 2240 – 1050 =1190
Req %=1190/3500*100=34%
