Correct Answer: Option B

Time = (24 + 31 + 18) days = 73 days

= 73 / 365 year = 1/ 5 year.

P = ₹ 3000 and R = 6% p.a = 25/4 % p.a.

S.I. = ₹ 3000 x 25/4 x 1/5 x 1/100 = ₹ 37.50

A
₹ 112
B
₹ 118.50

Let the present worth be ₹ X. Then, S.I. = ₹ (132-X)

∴ ₹ X x 5 x 2
100

= ₹ 132- X

<=> 10X = 13200 - 100X

<=> 110X = 13200

<=> X = 120

Question 7

12 x 3

Question 8
₹ 800 becomes Rs. 956 in 3 years at a certain rate of simple interest. If the rate of interest is increased by 4%, what amount will ₹ 800 become in 3 years ?

A
₹ 1020.80
B
₹ 1025
C
₹ 1052
D
Data inadequate
E
None of these
Correct Answer: Option C

S.I. = ₹ (956 - 800) = ₹ 156.

∴ Time = 100 x 156 years = 3 years.
800 x 3

= 6%

New Rate = 6 + 4% = 10%.

New S.I. = ₹ (800 x 21/2 x 3/100)

= ₹ 252.

New amount = ₹ (800 + 252) = ₹ 1052

Question 9
In how many years, ₹ 150 will produce the same interest @ 8% as ₹ 800 produce in 3 years @ 4% ?

A
6
B
8
C
9
D
12
Correct Answer: Option C

P = ₹ 800, R = 4% = 9/2%,

T = 3 years, Then,

S.I. = ₹ (800 x 9/2 x 3/100) = ₹ 108.

Now, P = ₹ 150, S.I. = ₹ 108, R = 8%.

Time = 100 x 108 years = 9 years.
150 x 8

Question 10
