Question 11 of 20
11. Question
A shopkeeper sells the transistors at 15% above its cost price. If he had bought it 5% more than what he paid for it and sold it for Rs. 6 more, he would have gained 10%. The cost price of the transistor is?
Correct
Answer c
Let the cost of the transistor be x
CP = x* 105/100= 105x/100
SP= 115x/100+ 6
Profit percentage= (SP- CP)/CP *100
10= (115x/100+6 – 105x/100)* 100/(105x/100)
10= (10x+600)100/105x
105x=100x+6000
5x= 6000
x= 1200
Incorrect
Answer c
Let the cost of the transistor be x
CP = x* 105/100= 105x/100
SP= 115x/100+ 6
Profit percentage= (SP- CP)/CP *100
10= (115x/100+6 – 105x/100)* 100/(105x/100)
10= (10x+600)100/105x
105x=100x+6000
5x= 6000
x= 1200
Question 12 of 20
12. Question
The difference between the simple interest and compound interest for 3 years at 8 % per annum is Rs. 433.664. Find the sum?
Correct
Answer a
The difference between the simple interest and compound interest for 3 years is,
Difference = [Sum* r^{2} * (r + 300)]/100^{3}
433.664 = [Sum*64*308]/100^{3}
Sum = (433.664*100*100*100)/(64*308)
Sum = Rs. 22000
Incorrect
Answer a
The difference between the simple interest and compound interest for 3 years is,
Difference = [Sum* r^{2} * (r + 300)]/100^{3}
433.664 = [Sum*64*308]/100^{3}
Sum = (433.664*100*100*100)/(64*308)
Sum = Rs. 22000

Question 14 of 20
14. Question
Two men undertook to do a piece of work for Rs. 2520. One alone could do it in 9 days and the other can do it in 6 days while with the assistance of a boy, work gets completed in 3 days. Find the share of boy?
Correct
Answer d
(1/9) + (1/6) + 1 boy = (1/3)
1 boy = (1/3) – [(1/9) + (1/6)]
1 boy = (1/3) – (5/18) = (6 – 5)/18 = 1/18
The share of two men and a boy = (1/9) : (1/6) : (1/18)
= > 2 : 3 : 1
6’s = 2520
1’s = 420
The share of boy = Rs. 420
Incorrect
Answer d
(1/9) + (1/6) + 1 boy = (1/3)
1 boy = (1/3) – [(1/9) + (1/6)]
1 boy = (1/3) – (5/18) = (6 – 5)/18 = 1/18
The share of two men and a boy = (1/9) : (1/6) : (1/18)
= > 2 : 3 : 1
6’s = 2520
1’s = 420
The share of boy = Rs. 420
Question 15 of 20
15. Question
Three – seventh of a number is equal to five-sixth of another number. The difference of these two numbers is 68. Find the numbers?
Correct
Answer a
(3/7) of a number = (5/6) of another number
(3/7)*x = (5/6)*y
(x/y) = (7/3)*(5/6) = 35/18
X : y = 35 : 18
17’s = 68
1’s = 4
The numbers are = 35*4 and 18*4 = 140 and 72
Incorrect
Answer a
(3/7) of a number = (5/6) of another number
(3/7)*x = (5/6)*y
(x/y) = (7/3)*(5/6) = 35/18
X : y = 35 : 18
17’s = 68
1’s = 4
The numbers are = 35*4 and 18*4 = 140 and 72
