The price of a cycle is reduced by 25 per cent. the new price is reduced by a further 20 per cent. the two reductions together are equal to a single reduction of
a. 45%
b. 40%
c. 35%
d. 32.5%
e. 30%

It should be 40 percent.

You can think of it as starting with 100 as in 100 dollars or 100 tic tacs

If you take away 25%, you take away 25 tic tacs and now you only have 75.

From your 75, you take away 20% which is equal to 15. 75- 15=60

If you look at the end result of 60, you can see that that is 100 - 40 so 40% of the total was taken off
