__Solution:__

**1).**S.I = (P × r × t) / 100

= (5000 × 10 × 3) / 100 = Rs. 1500

Amount payable after 3 years = 5000 + 1500 = Rs. 6500

**Answer: b)**

**2).**S.I = 675 = P × (15 / 100) × (5 / 2)

P = (675 × 100 × 2) / (15 × 5)

P = Rs. 1800

**Answer: c)**

**3).**Interest for a period of 3 years = 1875 – 1650 = Rs. 225

Interest for 1 year = 225 / 3 = Rs. 75

Interest for 2 years = 75 × 2 = Rs. 150

Amount after 2 years = 1650

Principal = 1650 – 150 = Rs. 1500

And rate of interest = (75 / 1500) × 100 = 5% per annum

[ S.I for 1 year = (P × r × t) / 100

75 = (1500 × r × t) / 100 ]

**Answer: a)**

**4).**Amount = P + Interest

15500 = P + (P × 12 × 2) / 100

15500 = (124 / 100)P

P = 12500

**Answer: b)**

**5).**Method 1 :

When the sum doubles itself, means interest equal to amount of principal is earned in 6 years.

This means

SI = P in 6 years [then only Amount = P + P = 2P]

Now, SI should be equal to 5P such that amount becomes 6P

So, SI is P in 6 years, it would be 5P in 6 × 5 = 30 years

Method 2:

Let the principal amount = P

2P = P + (P × 6 × r) / 100

P = (6 × P × r) / 100

r = (100 / 6)% per annum

Finding when amount becomes 6 times:

6P = P + [(P × 100 × t) / 600 ]

5P = (P × t) / 6

t = 30 years

**Answer: d)**

**6).**Let the amount lent to Shahid =x, then

[ x + (x × 10 × 5) / 100 ] + [ (10500 – x) + (10500 – x)15 × 5 ) / 100 ]

= Rs. 17,375

(3 / 2)x + 18375 – (7 / 4)x = 17375

-(1 / 4)x + 18375 = 17375

x = Rs. 4000

**Answer: d)**

**7).**P + (P × (8 / 100) × 4) = 5280

(33 / 25)P = 5280

P = Rs. 4000

Amount payable after 3 years

= 4000 + [ 4000 × (8 / 100) × 3] = Rs. 4960

**Answer: b)**

**8).**Let the sum borrowed at the rate of 12 p.c.p.a be Rs. x

Sum borrowed at 10 p.c.p.a = Rs. (30000 – x)

Simple interest = Rs. (36480 – 30000) = Rs. 6480

According to the question,

[(x × 2 × 12) / 100] + [((30000 – x) × 2 × 10) / 100] = 6480

24x + 600000 – 20x = 648000

4x = 648000 – 600000 = 48000

x = 48000 / 4 = Rs. 12000

**Answer: d)**

**9).**S.I = (P × r × t) / 100

8736 = (P × 6 × 8) / 100 = (8736 × 100) / (6 × 8)

= Rs. 17450

**Answer: d)**

**10).**Method 1:

We are given S.I = (30 / 100) P in 6 years, so

To make S.I equal to P : multiply (30 / 100) P by (100 / 30)

S.I = (30 / 100)P × (100 / 30) in (6 × 100) / 30 years

S.I = P in 20 years

Method 2 :

30 / 100 P = (P × 6 × r) / 100

r = 5 %

finding time when S.I = P

P = P × (5 / 100) × t

t = 20 years

**Answer: a)**
