Answer 1

Step-by-step explanation:

let principle to be x

si=(x×95×1113 )/1000

si=

p-si =1113

Answer 2

Step-by-step explanation:

Given At 9.5% simple interest per annum a sum of money becomes 1113 in  9 years. The sum initially invested was

• We know that S.I = P x R x T / 100
• So simple interest will be 1113.
•           So 1113 – P = P x 9.5 x 9 / 100
•          So 111300 – 100 P = 85.5 P
• So 85.5 P + 100 P = 111300
• 185.5 P = 111300
• Therefore P = 111300 / 185.5
•         P = 600

So the sum invested will be Rs 600
