vikas deposits Rs 1350 in a bank at 5% per annum and Rs 1150 in another bank at 6% per annum. find the rate of interest on the whole sum?​

Answer 1

Total sum = 2500

Rate of interest= 11

Answer 2

Rate of interest on whole sum is 5.46%.

Step-by-step explanation:

Since we have given that

Sum of first deposits = Rs. 1350

Sum of second deposits = Rs. 1150

Rate of interest for first = 5%

Rate of interest for second = 6%

According to question, we get that

$\dfrac{1350\times 5\times 1}{100}+\dfrac{1150\times 6\times 1}{100}=\dfrac{(1350+1150)\times R\times 1}{100}\\\\67.5+69=25R\\\\136.5=25R\\\\R=\dfrac{136.5}{25}\\\\R=5.46\%$

Hence, Rate of interest on whole sum is 5.46%.
