A. 83 1/3
B. 16 2/3
C. 90
D. 60
p = 6q.
Thus, q is less than p by 5q
q is less than p by (5q/6q x 100)% = 83 1/3 %
A. 50
B. 30
C. 40
D. 13
Work done by 4 men and 6 women in 1 day = 1/8
Work done by 3 men and 7 women in 1 day = 1/10
Let 1 man does m work in 1 day and 1 woman does w work in 1 day. The above equations can be written as
4m + 6w = 1/8 —(1)
3m + 7w = 1/10 —(2)
Solving equation (1) and (2) , we get m=11/400 and w=1/400
Amount of work 10 women can do in a day = 10 × (1/400) = 1/40
Ie, 10 women can complete the work in 40 days
A. 8%
B. 10%
C. 16%
D. 20%
A. Rs.3600
B. Rs.4000
C. Rs.4500
D. Rs.3000
Explanation:
X * (90/100) * (80/100) * (75/100) = 1944
X * 0.9 * 0.8 * 0.75
X = 1944/0.54
X = 3600
A. 32%
B. 42%
C. 52%
D. 62%
Explanation:
Total = 100
T= 40 NT= 60
40*(60/100)=24 60*(40/100)=24
24 + 24 = 48 => 100 – 48 = 52%
A. 1200 m²
B. 1500 m²
C. 12000 m²
D. 15000 m²
Actual length
= 30*500 cm Actual breadth
= 20*500 cm Actual area
= 30*20*500*500 = 15000 m²
A. Rs. 2800
B. Rs. 2100
C. Rs. 4200
D. Rs. 8400
Explanation:
2X + Y = 7000
X + 2Y = 9800
Solving (i) and (ii), we get Y = 4200
