A sum was invested for 3 years at simple interest at a certain rate, had it been invested at 4% higher rate of interest, it would have fetched Rs 600 more. What was the sum invested?
For 3 yrs=>Rs 600 more
For 1 Yr=>Rs 200 more
Assume invested amount is Rs 100.@4% higher rate , So we will get Rs 4 extra.
To get Rs 200 extra,we need to invest 200/4=50 times of Rs 100 ie Rs 5000
Ans is Rs 5000/-
Ahaan lent Rs 1200 to Bhargav for 3 years at certain rate of simple interest and Rs 1000 to Pulkit for the same time at the same rate.
If he gets Rs 50 more from Bhargav than from Pulkit , then what is the percent rate ?
