5 years ago, Trishika was 10 yrs old. Then, Jay was 3 x (10) yrs old = 30x 3 years after means 8 years after. TrishikaÃ¢Â€Â™s age = 10 8 = 18 yrs. JayÃ¢Â€Â˜s age = (30x) 8 yrs. Total = 18 (30x) 8 = 26 30x Answer-(D) (26 30x) years old

A.quarter of 16 is 4 and 3/4 of that is 3,so answer is A,3

Class : Class 3

Ans 3:

Class : Class 7
3/4th of quater is 3/4 x 1/4 = 3/16, therefore the answer is A

Class : Class 4

Ans 5:

Class : Class 4
answer is D A. 3/16 which is in lowest form B.4/16 =1/4 C.2/16=1/8 D.12/16=3/4

Ans 6:

Class : Class 6
Answer is A because the questions asks 3/4 of Quarter of traiangle i.e. 1/4th. So it is basically asking 3/16 of the triangle, hence, A.

yes u are right . it should be (B)

Ans 8:

Class : Class 10
Option C is correct because 0/(-7)=0 is wrong as when zero is divided by any other number, the answer is not defined but when any number is divided by zero, the answer is zero.
