What was the amount of money donated to a certain charity?

(1) Of the amount donated, 40 percent came from corporate donations. This implies that of the amount donated, 60 percent came from noncorporate donations. Not sufficient.

(2) Of the amount donated, $1.5 million came from noncorporate donations. Not sufficient.

(1)+(2) 0.6*{total} = $1.5 million. We can solve for {total}. Sufficient.

Answer: C.

1) we don't know what 40% is equal to hence we cannot deduce the total amount
2)we don't how much came from non corporate donations hence also insuff.

1+2
we know 40% from corporate donations hence 60% from non corporate donations
60% = $1.5 Million
hence we can find 100%

1+2 Sufficient
Answer C

(1) Of the amount donated, 40 percent came from corporate donations.
(2) Of the amount donated, $1.5 million came from noncorporate donations.



Statement 1) No actual value of money mentioned but the question asks about amount of money. Not Sufficient.
Statement 2) Though the value of money is specified, but the relationship of "noncorporate donations" with the "money donated" is not specified. So Not Sufficient.

Combining the two statements, we know $1.5 million corresponds to 60% (assuming "corporate donations" and "noncorporate donations" are mutually exclusive - Kind of open to interpretation), total money can be calculated. Hence option C)

Helpl me with one kind of confusion. It is not explicitly given that the total money donated to charity comprises of only corporate and non corporate donation.Then how can we assume that both sum up to total money.

All donations are either corporate or noncorporate, how else? Consider this, are there any other colors but black and non-black? It's as simple as this.
