Answer 1

answer is.9000 for muldhan ×samay×dar/100

Answer 2

Solution

Given :-

• P = 30,000
• R = 10%
• T = 3 Years

Find :-

• the difference between simple intrest and compound intrest .

Explanation

Using Formula

★ S.I. = ( P × R × T)/100

★C.I. = p( 1 + R/100)^T - P

First Calculate S.I.

==> S.I. = 30,000 × 10 × 3/100

==> S.I. = 300 × 10 = 3

==> S.I. = 9000

Again, Calculate C.I.

==> C.I. = 30,000(1 + 10/100)³ - 30,000

==> C.I. = 30,000( 1 + 1/10)³ - 30,000

==> C.I. = 30,000[(10+1)/10]³ -30,000

==> C.I. = 30,000( 11/10)³ - 30,000

==> C.I. = 30,000 × 11/10 × 11/10 × 11/10 - 30,000

==> C.I. = 30 × 11 × 11 × 11 - 30,000

==> C.I. = 39,930 - 30,000

==> C.I. = 9,930

Now, calculate Difference between C.I. & S.I.

= C.I. - S.I.

= 9,930 - 9,000

= 930

Hence

• Difference between C.I. & S.I. will be =Rs. 930
