Question

if 460 Rupees amounts to 640 rupees in 6 years what will it amount to in 2 years at the same rate​

Answer 1

Step-by-step explanation:

If 460 amounted to 640, then 640-460= 180

This means in 6 years 180 got added

Then in 2 years how much will be added ?

180/6 = x/2

By cross multiplication,

360= 6x

By dividing by six,

x= 60

So it increases 60 rupees every two years

Now, 460+60= 520

Therefore it will amount to 520 rupees in two years.
