Question

4. Rupees 4,000 amount to 5,000 in 8 years;
in what time will 2,100 amount to * 2,800 at
the same rate ?​

Answer 1

Answer:

10 years and 8 months

Step-by-step explanation:

A = 5000 ....P = 4000

I = A - P = 1000

T = 8 years

R = (100 × I ) / ( P × R ) = 25/8%

in 2nd case

A = 2100 P = 2800

I = 2800 - 2100 = 700

R = ( 100 × I ) / ( P × R ) = 32 / 3 years

= 10.2/3 years × 12 months

after some calculations result will be

10 years and 8 months
