There are three amounts a,b and c, such that b is the simple interest on c and c is the simple interest on a. Which of the following must always be true?

a,b and c are the three sums of money such that b is the simple interest on a and c is the simple interest on b for the same time and same rate. Which is the following is correct? (a) abc=1 (b) c^2 =ab (c) b^2 =ac (d) a^2 =bc

a,b and c are the three sums of money such that b is the simple interest on a and c is the simple interest on b for the same time and same rate.Which is the following is correct? abc=1(b)c^(2)=abb^(2)=ac(d)a^(2)=bc

Three amounts x, y and z are such that y is the simple interest on x and z is the simple interest on y. If in all the three cases, rate of interest per annum and the time for which interest is calculated is the same, then find the relation between x, y and z.

If x , y , z are three sums of money such that y is the simple interest on x , z is the simple interest on y for the same time and at the same rate of interest, then we have x^2=y z (b) y^2=x z (c) z^2=x y (d) x y z=1

Find the rate of simple interest in percent per annum if the simple interest of a principal is 3/5 part of the amount in 10 years.

If an amount of Rs 5,000 earned a simple interest of Rs 500 over 2years, what is the rate of simple interest?

A principal amount of Rs. 45000 gives Rs. 54000 as a simple interest in 6 years. Find the simple interest on half of the principal amount for 3 years at the same rate of interest?
