Question

calculate the amount and conpound interest on RS 15000 for 1½ years at 10 percentage per annum compounded annually ​

Answer 1

Given

Principal (P) = Rs 15000

Rate (R) = 10% p.a.

Period (n) = 2 years

Hence,

Amount (A) = P {1 + (R / 100)}n

= Rs 15000 {1 + (10 / 100)}2

On further calculation, we get,

= Rs 15000 × (11 / 10) × (11 / 10)

We get,

= Rs 18150

Therefore,

Compound interest = Amount – Principal

= Rs 18150 – 15000

We get,

= Rs 3150

Answer 2

Step-by-step explanation:

• p 15000
• t-1 and half years
• rate 10 percent
• C.I - A-P
• A=P(1+R/100) power t
• 2 years
• 15000(1+10/100)power 2
• 15000×(110/100) power 2
• 15000×110/100×110/100
• 15×110/1×110/100
• 15×110×11
• 18,150
• Amount has come now find C .I.
• A-P
• 18,150-15,000
• 3,150
