Answer 1

Answer:

67. given least cost is 12.

and pen<pencil & eraser>pencil

so pen<pencil<eraser

hence the least one will be pen which is 12

Right answer is A

68. to get this answer we have to use each of the options given here.

a. pen cost is 12. and we know pen<pencil so pencil cost can't be 12.

b. if pencil cost is 13 then eraser cost = 41-(12+13)=16 which is divisible by 4 hence cost of pencil can't be 13.

c. if pencil cost is 14 then eraser cost = 41-(12+14)= 15 which is not divisible by 4 and also pen<pencil<eraser is satisfied. so pencil cost can be 14.

d. if pencil cost is 15 then eraser cost = 41-(12+15) = 14 which is not divisible by 4 but pen<pencil<eraser is not satisfied. so 15 can't be cost of pencil.

So right answer is C
