Embibe Experts Solutions for Chapter: Arithmetic, Exercise 6: Exercise 6

If compound interest received on a certain amount in the $3rd$ year is Rs. $1240$, what will be the compound interest for the $4th$ year on the same amount at $9\%$ rate of interest?

An amount lent at  \( x\% \) annually for 3 years. If the same amount is lent at  \( (x+3)\% \)  annually for the same time period, then Rs. 1296 more will be earned as interest. The amount is -

In $4$ yr at Simple interest the principal increases by $32\%$ . What will be the compound interest earned on Rs. $24000$ in $3$ yr the same rate?

At simple interest a sum becomes $\frac{49}{40}$ of itself in $2\frac{1}{2}$ years. The rate of interest per annum is

A man deposits $Rs.5,600$ in a bank at $\frac{15}{4}\%$ simple interest. After $6$ months he withdraws $Rs.2400$ together with interest and after $6$ months, he withdraws the remaining money. The total amount, he gets as interest is:

A person lent certain sum of money at $5\%$ per annum simple interest and in $15$ years the interest amounted to $Rs. 250$ less than the sum lent. What was the sum lent (in $Rs.$)?

Raju borrows Rs. 25000 for 2 years at 5% p.a. simple interest. He immediately lends it to Rani at $$7\frac { 1 }{ 2 } $$ % P.a. for 2 years. Find his gain in the transaction per year ?

The compound interest on a sum of money for $2$ Years is $₹410$ and the simple interest on the same sum for the same period and at the same rate is $₹400$. Find the rate of interest ?
