Its a 3 entity set problem. where Total (distinct) = A + B + C - (A and B) - (B and C) - (A and C) + (A and B and C) so, A = B = C = 8 (each has 8 members) (A and B) + (B and C) + (A and C) = 5 * 3 = 15 ( each has 5 common with one of the other) Common among all 3 = 4 so, Total (distinct) = 8 + 8 + ...

I used the same approach as Morgoth but I'll try add more reasoning about A (3^27)(5^ 10)(z) = (5^8 )(9^14)(x^y) This can be simplified as (3^27)(5^ 10)(z) = (5^8 )(3^28 )(x^y) and finally, after dividing bot parts by (3^27)(5^8 ) we'll get (5^2)(z) = (3)(x^y) z should ne equal to 3 (because of the...

I think, we can solve it as 560 - n* ( 60) = 52* (10 - n) where n is the number of oranges removed. 1. Total cost of 10 (apple + orange) = 56 * 10 = 560 2. Let say n oranges are removed, so the cost decreased by n * 60 3. Now, if n oranges are removed, then Total fruits = 10 - n 4. Total cost, if th...

So, what we do is take all powers of 2, which are small than the factorial number ( in this case 30 ) So, we h...

I would go with 'C'. This seems like an overgeneralization. The advertisement states that the PZ 1000 has the fewest injuries per accident in its group and then proceeds to conclude that the PZ 1000 is one of the safest cars available. Just because it is the safest car in its class does not mean th...
