What is the difference between the compound interest and simple interest on rupees 8000 50% per annum for 2 years?

University Grants Commission (Minimum Standards and Procedures for Award of Ph.D. Degree) Regulations, 2022 notified. As, per the new regulations, candidates with a 4 years Undergraduate degree with a minimum CGPA of 7.5 can enroll for PhD admissions. The UGC NET Final Result for merged cycles of December 2021 and June 2022 was released on 5th November 2022. Along with the results UGC has also released the UGC NET Cut-Off.  With tis, the exam for the merged cycles of Dec 2021 and June 2022 have conclude. The notification for December 2022 is expected to be out soon. The UGC NET CBT exam consists of two papers - Paper I and Paper II. Paper I consists of 50 questions and Paper II consists of 100 questions. By qualifying this exam, candidates will be deemed eligible for JRF and Assistant Professor posts in Universities and Institutes across the country.

Given : P = Rs. 8,000, R = 5%, T = 2 years
For simple interest,

S.I. = `[ "P" xx "R" xx "T"]/100`

= `[8,000 xx 5 xx 2]/100`

= Rs. 800

For compound interest,

`"A" = "P"( 1 + r/100 )^n`

`"A" = 8,000( 1 + 5/100 )^2`

= `8,000 xx 21/20 xx 21/20`

= Rs. 8,820

C.I. = A - P      = Rs. (8,820 - 8,000)

      = Rs. 820

Now, C.I. - S.I. = Rs. ( 820 - 800 ) = Rs. 20.
Thus, the difference between the compound interest and the simple interest is Rs. 20.
