Option D
45% 𝑜𝑓 600+?% 𝑜𝑓 480=390
=>45/100 𝑜𝑓 600+?/100 𝑜𝑓 480=390
⇒270+4.8×?=390
=> ? =(390−270)/4.8 = 25

2. 4(2/3)+7(1/6)−5(2/9)= ?
3(8/13)
2(9/11)
6(11/18)
4(13/15)
3(10/17)
Option C
4(2/3)+7(1/6)−5(2/9)= ?
=>? = 14/3+43/6−47/9
= (84+129−94)/18
= 119/18 = 6(11/18)

3. [30% 𝑜𝑓 {(80% 𝑜𝑓 850)÷34}]= ?

Option A
[30% 𝑜𝑓 {(80% 𝑜𝑓 850)÷34}]= ?
=>?=[30/100×{(80/100×850)÷34}]
=[30/100×{680÷34}]
=[30/100×20] = 6

4. ? % of 800 = 293 – 22% of 750

Option D
? % of 800 = 293 – 22% of 750
=>(800×?)/100=293−(750×22)/100
⇒8× ?=293−165=128
⇒ ?=128/8 =16

5. 65% 𝑜𝑓 240+ ?% 𝑜𝑓 150=210

Option B
65% 𝑜𝑓 240+ ?% 𝑜𝑓 150=210
=>65/100 𝑜𝑓 240+?/100 𝑜𝑓 150=210
⇒156+1.5×?=210
=>?=(210−156)/1.5 = 36

6. Present age of A is 3 years less than present age of B. Ratio of B’s age 5 year ago and A’s age 4 year hence is 3 : 4 then find present age (in years) of A.
30
40
20
10
50
Option C
Let B’s age = 𝑥
So, A’s age = 𝑥−3
=>(𝑥−5)/(𝑥+1) = 3/4
=> 𝑥 = 23
A’s age = 23−3 = 20 yrs.

7. The profit earned on selling an article for Rs.1000 is equal to the loss incurred on selling the same article for Rs.500. At what price should it be sold to earn a profit of 24%?
Rs.820
Rs.900
Rs.740
Rs.930
Rs.880
Option D
Let the CP be Rs.x. (1000 – x) = (x – 500)
=>x = 750
Required SP = 750*1.24 = Rs.930

8. Tap A is 50% more efficient than Tap B. Both the taps together can fill the tank in (48/5) hours. Find the time taken by Tap C which is 60% more efficient than Tap B, to fill the tank alone.
18 hours
16 hours
12 hours
10 hours
15 hours
Option E
Time taken by A and B to fill the tank be x/1.5 and x hours resp.
Now, 1/x + 1.5/x = 5/48
=>x = 24
Time taken by C = 24/1.6 = 15 hours

9. Income of Anil is Rs.25000 per month. He spends 25% on food and 35% on rent. If 50% of the remaining amount is spent by him on entertainment and rest of the amount is saved by him. Find his monthly savings (in Rs.).
Rs.5000
Rs.7000
Rs.6000
Rs.8000
Rs.4000
Option A
Expense on food and rent = 25% + 35% = 60%
Expense on entertainment = 0.5*(100-60)% = 20%
Savings = 100% – (60%+20%) = 20%
Anil’s savings = 0.2*25000 = Rs.5000

2/5
7/9
1/3
4/5

Probability that no ball is green = (10C1*9C1)/(15*14)
= 3/7
