SOLUTIONS

S4. Ans.(a)
Sol. For the last 5 days 200 men worked in place of 100 men,
200 × 5 = 100 × x
x = 10 days (This means 100 men would have taken 10 days)
hence, they will take 5 day more than stipulated time
S5. Ans.(b)
Sol. ∴ 10 women can complete the work in 7 days.
∴ 70 women can complete the work in 1 day.
Again,
∴ 10 children can complete the work in 14 days.
∴ 14o children can complete the work in 1 day.
∴ 70 women = 140 children
∴ 1 women = 2 children
∴ 5 women + 10 children
(10 + 10) children = 20 children
Now, 140 children can complete the work in 1 day
∴ 20 children can complete in 140/20 = 7 days.
S7. Ans.(c)
Sol. A:B=4:5 = 8:10
B:C=2:3 = 10:15
So,    A:B:C=8:10:15
C=800×15/8=1500
S8. Ans.(d)
Sol. Let the earnings of A and B be 8x &Rs. 9x respectively.
Now, after changes in their earnings,
A’s earning =150/100×8x = Rs. 12x
B’s earning =75/100×9x= Rs. 27x/4
From above data ,We cannot find the answer of the given question
Hence, answer will be can’t be determine
S9. Ans.(a)
Sol. 16000 × 3 + 11000 × 9 : 12000 × 3 + 17000 × 9 : 21000 × 6
48000 + 99000 : 36000 + 153000 : 126000
147000 : 189000 : 126000
147 : 189 : 126
49 : 63 : 42
Total of the terms of ratios = 154
B’s profit – C’s profit = 63 – 42 = 21
21/154× 26400=3600

S12. Ans.(d)
Sol. Mahesh present age = 5 years
So, Anup’s present age = (5 – 2) = 3 years
According to question, (R –  6)/18=3
R = 18 × 3 + 6 = 54 + 6 = 60 years
S13. Ans.(c)
Sol. 4P = P(1+r/100)^2
2 = 1 + r/100
r = 100%
S14. Ans.(b)
Sol. Quantity of zinc in the mixture
=2(1/3)+3(1/4)=2/3+3/4=( 8 + 9)/12=17/12
Quantity of copper in the metal
=3+2-17/12=5-17/12=43/12
∴ ratio =17/12 ∶43/12=17∶43 Join India's largest learning destination
