Step - by - step explanation :

Q.10

Let the principal be Rs.100

So the amount will be Rs. 300

interest = amount - principal

= 300 - 100

= Rs.200

S.I = PNR/100

200 = 100 × 8 × N/100

200 = 8N

N = 200/8

N = 25 yrs

Q.11

Let original price be Rs.x

So

x - 7% of x = 465

x - 7x/100 = 465

93x/100 = 465

x = 465 × 100/93

x = Rs.500
