8. A tank is 2/6 full. Adding 16 litres of water to it makes it 6/7 full. What is the capacity of the tank?
You answered: 32 litres
Incorrect

Correct answer: 35 litres"

2/6 * 35 = 70/6

6/7 * 35 = 30

30 - 70/6 = 180/6 - 70/6 = 110/6 = 18+2/6 = 18+13 != 16

"10. A group of friends decided to spend Rs 96 on eatables at a picnic. However, 4 friends could not come. So, remaining friends had to spend Rs 4 extra per head. How many friends actually attended the picnic?
You answered: 8
Incorrect

Correct answer: 12"

If actually 12 attended, then each spent 96/8 = 12
and full group is (12 + 4) = 16, so originally each was to spend 96/16 = 6,
(12-6) = 6 != 4
