Question

At what rate of simple interest will 15,000
become Rs 30,000 in four years?​

Answer 1

P= 15000

total amount = 30000

SI = 30000- 15000

= 15000

(PTR)/100= 15000

15000(4)(R) = 1500000

4R = 1500000/15000

4R = 100

R = 100/4

= 25%

Answer 2

Answer:

SI = P × R × T / 100

30000 = 15000 × 4 × R / 100

R = 30000/600

= 50 %
