Sherry's math test had 100 problems, 40 arithmetic, 30 algebra, 30 geometry problems. Although he answered 30% of arithmetic, 40% of algebra and 70% of geometry problems correctly, still he got less then 50% marks. How many more questions he would have to answer more to get passed.

Arithmetic: 30% of 40 = 12

Algebra : 40% of 30 = 12

Geometry : 70% of 30=21

Total correct = 12+12+21=45

50-40=5 marks needed to pass.

In following question, a number series is given with one term missing. Choose correct alternative

1, 2, 3, 6, 9, 18, x , 54

1, 2, 3, 6, 9, 18, x , 54

The numbers are alternatively multiplied by 2 and 3/2.

So, 1 X 2 = 2, 2 X 3/2 = 3,

3 X 2 = 6, 6 X 3/2 = 9,

so missing number = 18 X 3/2 = 27.
