Answers:
1. 2
So,
1/5x = 8 ---> x = 40
3/20y = 9 ---> y = 60
1/4z = 20 ---> z= 80
Ratio of their salary's = 40 : 60 : 80 = 2 : 3 : 4
Ram's salary = 3/9 × 81000 = ` 27000
2. 3
Total increase in population percentage = 308/5600 * 100 = 11/2%
Male : Female = 3 : 2
Number of Male population = 3360
Number of Female population = 2240
Non–working population = 3360 * 1/3 + 2240 * 1/2 = 1120 + 1120 = 2240
3. 3
Given
2 × Rahul's capital = 3 × Nayan's capital
Rahul's capital : Nayan's capital= 3 : 2
And,
Nayan's capital = 4 × Pooja's capital
Nayan's capital : Pooja's capital = 4 : 1
Ratio of capitals of Rahul ,Nayan and Pooja
= 6 : 4 : 1
Nayan's share of profit = 4/11 * 22275 = Rs. 8100
4. 3
There 13 cards of diamond (including one queen)
and there are 3 more queen.
Required probability = (13 + 3)/52 = 4/13
5. 4
Efficiency of P + Q = 5 and efficiency of Q + R = 4
and P : R = 2 : 1
So efficiency of P, Q and R will be
P = 2 unit/day
Q = 3 unit/day
R = 1 unit /day
7
Required time taken to complete the work together = 60/(2+3+1) = 10 days
6. 4
Quantity of Guava available at vendor A
= 2400 × 10/100 = 240 kg
Quantity of Guava at available at vendor B
= 2000 × 16/100 = 320 kg
So, required difference = 320 – 240 = 80 kg
7. 2
At vendor A,
Cost of Mango = 130 × 2400 × 24/100 = Rs. 74880
Cost of Apple = 140 × 2400 × 16 /100 = Rs. 53760
Cost of Orange = 80 × 2400 × 20/100 = Rs. 38400
So, required ratio = 7488 : 5376 : 3840= 39 : 28 : 20
128. 4; Quantity Mango available at vendor B
= 2000 × 24/100 = 480 kg
Quantity Mango available at vendor A
= 2400 × 24/100 = 576 kg
So, required percentage = 480/576 * 100 = 83%
9. 4
Cost of all fruits available at vendor A
= (2400 × 24/100 × 130 + 2400 × 16/100 × 140
+ 2400 × 10/100 × 68 + 2400 × 20 /100 × 80
+ 2400 × 30/100 × 115)
= 24× [24 × 130 + 16 × 140 + 10 ×68 + 20 × 80 + 30 × 115]
= 24× [3120 + 2240 + 680 + 1600 + 3450] = Rs. 266160
Cost of all fruits available at vendor B
= (2000 × 24/100 × 130 + 2000 × 14/100 × 140 + 2000 ×
16/100 × 68 + 2000 × 20/100 × 80 + 2000 × 26/100 × 115)
= 20[24 × 130 + 14 × 140 + 16 × 68 + 20 × 80 + 26 × 115]
= [3120 + 1960 + 1088 + 1600 + 2990] × 20 = ` 215160
So, required difference = Rs. 51000
10. 5
Quantity of Orange available at Vendor A = 2400 × 20/100 = 480kg
Quantity of Apple available at Vendor B = 2000 × 14/100 = 280 kg
So, required percentage = (480 - 280)/280 * 100 = 71.43%
