Answer:

Amount: Rs. 2315.25

Compound Interest: Rs. 315.25

Principal: Rs. 2000

Time: 1.5 years

Rate% p.a.: 10

Since the amount is compounded half yearly, rate becomes half and time gets doubled.

New Time: 1.5 × 2 → 3 years

New Rate% p.a.: 10/2 → 5

a=p × (1 + r/100)^n

2000 × (1 + 5/100)^3

→2000 × (1 + 1/20)^3

→2000 × [(20+1)/20]^3

→2000 × (21/20)^3

→2000 × 21/20 × 21/20 × 21/20

→2315.25

Amount: Rs. 2315.25

Compound Interest: Amount - Principal

→2315.25 - 2000

→315.25

Compound Interest: Rs. 315.25

Hence, Amount and Compound Interest are Rs 2315.25 and Rs. 315.25, respectively.

Answer:

We will discuss here about the conversion of minutes into hours. We know 60 minutes is equal to 1 hour, which is required to convert the measuring time from minutes to hours.

Solved Examples on Conversion of Minutes into Hours:

1. Convert 45 minutes into hours.

We know, 60 minutes = 1 hour

or, 1 minute = 1/60 hour

Therefore, 45 minutes = 45/60 hour = ¾ hour.
