When factoring, it's easier to "pick out" the GCF first because it makes it simpler to factor even further. Otherwise, you will be troubled with lots of numbers and variables, so it will just get confusing.
Given
Principal = Rs 700
Time = 6 months = 6/12 years = 1/2 years
Rate = 6 % p.a.
To Find
Amount
Formula
Amount = Principal + Simple Interest
So let us firstly find the Simple Interest,
S.I. = (P × R × T)/100
= (700 × 6 × 1)/ 100 × 2
= 7 × 3
= Rs 21
Hence;
Amount = 700 + 21
= 721 <u>Ans</u><u>.</u>
