Answer 1

answer is true

Step-by-step explanation:

Amount= P(1+R/100) raised to power n

A=15000(1+ 4/100) raised to power 2

A=15000( 1/1 + 4/100)2

A= 15000(100+ 4/100)2

A= 15000(104/100)2

A= 15000(26/25) raised to power 2

A=15000× 26/25 × 26/25.

A= ₹16,224

compounds interest= Amount-principle

= 16,224-15000

1224

simple interest= P×R×T/100

= 15000×4×2/100

1200

do the difference

compound interest - simple interest

= 1224- 1200

= 24

answer is true

Answer 2

Answer:

True

Step-by-step explanation:

$SI = \frac{15000 \times 4 \times 2}{100} = 1200$

$CI = 15000(1 + \frac{4}{100} {} ) {}^{2} \\ = 1224$

$CI - SI \: = 1224 - 1200 = 24$
