Question

Mary saves at the bank of Rs. 2.500.000,00 with interest rate of 16% per year. How long is Maria's money to be Rs. 2.600.000,00 ???

Answer 1

Amount of interest per year:
= 16% × Rs 2,500,000
= 16/100 x Rs 2,500,000
= Rs 400,000

Long saving
= (Rs 2.600.000 - Rs 2.500.000) / Rs 400.000 × 12 billion
= Rs 100.000 / Rs 400.000 × 12 billion
= ¼ × 12 billion=
= 3 billion

Answer 2

==============3 billion
