it can be option B but there is an other formula. Add all the digits of all the 4 options. Option A,B,C would be 27 but option D would be 26. That makes the difference between option A,B,C with D. So the answer is option D.

Corrected the question. Minus sign was missing

Solution:
David's current age = 3x -2
David's age eight years before = 3x -2 -8 = 3x - 10
Sally's age = David's age eight years before = 3x -10
Sally's age after 4 years = 3x - 10 + 4 = 3x -6

## Ans 3:

yes it should be 154

## Ans 4:

the correct answer is B. there are two small semicircles that form one circle when joined. so after joining it forms 1 circle with a diameter of 14 which means it has a radius of 7. area= 7*7*(22/7)= 154 in the big semicircle it has a diameter of 28 which means it has a radius of 14. area = (14*14*22)/(7*2) = 616 area of shaded part = 616-154= 462 thus the correct option is B
