But he did not seen he give extra 25% rupees to me. Now at last how much total money I had with me. Please u know answer only put. Please explain it in detail.

Answer 1

Answer:

P = Principal

R = rate% per annum

T = time

I = simple interest

A = amount

Formula for calculating simple interest is S.I = (P × R × T)/100

Important: Formula for calculating amount is A = P + I

Principal = $2000

Rate = 5% p.a.

T = 3 years

S.I = (P × R × T)/100

= (2000 × 5 × 3)/100

= $ 300

Amount = P + I

= $ ( 2000 + 300 )

= $ 2300

Answer 2

Answer:

Let P be the sum lent out at 15% and Q be the sum lent out at 4%. So Px.15x4 = Qx.04×10

Therefore, P:Q = 15x4/10x4 = 3:2.The total sum of Rs. 8000 is to be divided in the ratio of 3:2. This way the first sum is 8000x3/5 = Rs. 4800.
