Question

If X:Y=3:4,the value of xsquare y+X T-square: Xcube + Ycube is??

Answer 1

Answer:

answer is 12:13

Step-by-step explanation:

Divided by Ycube in Numerator & Denominator ,we get

( Xsquare /Ysquare )+X/Y : (Xcube /Ycube) +1

Putting X/Y=3/4 above, we get

(3/4)square + 3/4 : (3/4)cube+1

(9/16)+(3/4) :(27/64)+1

solving it, we get

(21/16)*(64/91) = 12/13

answer is 12:13
