Given:
(i) At the halfway point of a telethon, charity has raised one-quarters of total amount.
(ii) In the next 2 hours, the total amount raised doubles.
To find:
(i) The percentage of its target amount raised.
Solution:
Let the target amount be Rs 100.
Given that, in the halfway point, only one-fourth of the total charity money is raised.
So, total money raised = 1/4 * Rs 100
= Rs 25.
Again, it is given that in the next 2 hours, the total amount raised had doubled.
So, amount collected in these 2 hours = 2 * Money collected beforehand
= 2 * Rs 25
= Rs 50.
So, total money collected till now = Rs (25+50)
= Rs 75.
So, the percentage of its target amount raised
= [(Amount raised/Target money)*100]%
= [(75/100)*100]%
= 75%
Thus, 75% of the total money has been raised.
