Question

find the amount and compound interest : (a) Principle = 4800, Rate = 7.5 , Time = 1.5.

Answer 1

Answer:

▪️Amount = ₹5547

▪️Interest = ₹747

Step - by - Step Explaination:

▪️As we know,

▪️Compounded Amount :

▪️Method 1

▪️P₁ ( 1 + R/100 )ⁿ  

▪️Method 2

▪️a₁ =(p₁ * r / 100)+ p₁ = p₂ ;

▪️s.i₂ = (p₂ * r)

▪️at the end of second yr = a₂ = p₂ + s.i₂

▪️So,

▪️Given :

▪️Principle = rs. 4800

▪️Time ( n ) = 2 yrs.

▪️Rate = 15/2% or 7.5%

▪️Solution :

Solution :     ▪️  ( By method 1 )

▪️4800 ( 1 + 7.5/100 )²   {= A.}

▪️4800 ( 107.5 * 107.5 / (100)²

▪️4800 ( 1075 * 1075 ) / 100³

▪️5547000000/100³

▪️5547

▪️So, Amount is RS. 5547

▪️Then Interest = A - P = 5547 - 4800 = ₹747
