6. If 2/3 part of an article is sold at 30% profit, 1/4 part at 16% profit and remaining part at 12% profit and finally, there is a profit of Rs.75, then find the cost price of the article.
500
600
400
100
300
Option E
Here a = 2/3
b =1/4
x = 30 %
y = 16 %
z = 12 % and R = Rs. 75
Required CP of article
= (75*100)/(2/3*30+1/4*16+1/12*12)
= 7500/25
= 300

7. Two pipes can fill a tank in 20 and 24 minutes respectively and a waste pipe can empty 3 gallons per minute. All the three pipes working together can fill the tank in 15 minutes. What is the capacity of the tank?
150 gallons
120 gallons
130 gallons
100 gallons
80 gallons
Option B
Work done by the waste pipe in 1 minute
= 1/15 − ( 1/20 + 1/24 ) = 1/15 − 11/120 = −1/40
Volume of 1/40 part = 3 gallons
Volume of whole = (3 x 40) gallons
= 120 gallons.

8. Raju got married 8 years ago. His present age is 6/5 times his age at the time of his marriage. Raju’s sister was 10years younger to him at the time of his marriage. Find the present age of Raju’s sister.
40 years
18 years
20 years
38 years
35 years
Option D
Let Raju’s age at the time of his marriage = x years
Then from given data => x + 8 = 6x/5
x = 40.
Since got married 8 years ago, his present age = 48
His sister is 10 years younger
=> 48 – 10 = 38 years.

9. A sum of money at simple interest amounts to Rs. 14160 in 3 year. If the rate of interest is increased by 25%, the same sum amount to Rs. 14700 in the same time. Find the rate of interest.
7%
3%
5%
6%
4%
Option D
14160 = P + (P × R × 3)/ 100
=> 3PR/ 100 = 14160 – P
=> 14700 = P + (P ×1.25R × 3)/ 100
=> P + 5/4 × 3PR/100 = 14700
=> P + 5/4(14160 − P) = 14700
=> 4P + 70800 – 5P = 58800
=> P = 12000
=> 14160 = 12000 + (12000 × R × 3)/100
=> 14160 = 12000 + (120 × R × 3)
=> 14160 – 12000 = 360R
=> 2160 = 360R
=> R = 2160/360 = 6%

10. Twelve persons are seated at a circular table. Find the probability that 3 particular persons always seated together.
3/50
4/55
2/51
3/55
3/53
Option D
Total probability = (12-1)! = 11!
Desired probability = (10 – 1)! = 9!
Required Probability = (9! *3!) /11!
= 3/55
