Question

8) What sum lent out at 6¹/₄% per annum produces the same simple interest in 2 years as Rs2100 lent out at 5% per annum produces in 16 months?​

Answer 1

Answer:

Simple interest= 140

principal = 1120

Step-by-step explanation:

case 1

p = 2100

r = 5%

t = 4/3 yrs

SI = prt / 100

2100×5×4 / 100 × 3

SI = 140 rs

case 2

p = ?

r = 25/4 %

SI = 140 rs

SI = prt / 100

140= p×25×2 / 100 ×4

140 = p / 8

140×8=p

p = 1120

Answer 2

Answer:

SI=140

AMOUNT=1120

Step-by-step explanation:

Case 1:-

principal =2100

Rate=5%

Time=4/3

Si=P×R×T/100

=2100×5×4/100×3

SI=140

CASE 2=

RATE=25/4

SI=140

SI= P×R×T/100

=P×25×2/100×4

=P/8=140

P=140×8

=1120
