Hi Joy Shaha,

What is the source of this question? I ask because it's poorly-written and not in the proper 'style' that GMAT writers use. If you're studying for the GMAT, then you would likely find it useful to switch to more reputable practice resources.

1st method-
The simple interest would be defined on the basis of the sum of the A.P.
50000 + 47500 + 45000 + .... + 2500 = 525000
