Answer is 3:8. I would suggest you to assume the values of x and 6y (i assumed 2 and 24 respectively..). then calculate the area of rectangle(in my case 48 sq. cm).. then calculate the area of both triangles (i hope u can!) and find their ratio..

This is a trick everybody should know- 456 tens = 4560 . most of the people don't understand this part . Now pay attention to this 456 - _______ = 2456 ( 4560 - _______ = 2456 )Now __________ = 4560 - 2456 . If we do the following subtraction sum, we shall find out the answer i . e. 2104 meaning 4560 - 2456 = 2104

## Ans 2:

456 tens=4560-_=2456. You can find the answer by 4560-2456=2104.So the blank is =4560-2456=2104. This is the trick.

(C): 456 tens = 4560

Now, it is given that

4560 –  = 2456

∴  = 4560 – 2456
∴  = 2104
