Question

If 6400 amounts to 8320 in 2 years., what will 8600 amounts to in 5 years. at the
same rate percent per annum?​

Answer 1

Answer:

15050

Step-by-step explanation:

here let x be the increase rate

then S. I = Principle *rate*time/100

=6400*x*2/100

=128x

then

S I + Principle = amount

128x+ 6400 =8320

x=8320-6400/128

x=15%

so 8600 will amount = S I + Principle

=8600*15*5/100+8600

=6450+8600

=15050
