(1) He sold 35 large balloons
(2) He sold 25 small blue balloons


Given small red+ small blue +large red+ large blue = 108
we have to find out number of small red.

Statement 1: 35 large balloon sold
large red + large blue = 35
Small red + small blue + 35 = 108
Small red + small blue = 73.
There are 2 variable and one equation so statement 1 is not sufficient.
Statement 2 : small blue = 25
As we have to find the number of small red balloon, this statement does not give information about small red balloon's number.
So it is insufficient

Combining Statement 1 and 2 , i.e Small red + small blue = 73;small blue = 25 , we can find out the number of small red balloon.
small red+ 25 = 73
small red = 48

So answer is C

IMO C.

This is a 2x2 matrix problem and I solve it using the famous table method.

Since we know the sum of all balloons we can fill out the details and find the required subset.

Refer to attached image. R = Red, B = Blue, S = Small and L = large.

Kudos ! if you liked the explanation...
