If 30% of X = Y and 40% of Y = Z, then 30% of (X + Y) is: 1] 150% of Z 2] 275% of Z 3] 300% of Z 4] 325% of Z
Read Solution (Total 2)
-
- GIVEN,
30% OF X=Y, 40% OF Y=Z
(30/100)X=Y, (40/100)Y=Z
(3/10)X=Y, (4/10)Y=Z
X=(10/3)Y, Y=(10/4)Z
X=(10/3)(10/4)Z
X=(25/3)Z
THEREFORE, (30/100)(X+Y)====?
=(30/100)((25/3)Z+(10/4)Z)
=3.25Z
=325% OF Z - 5 years agoHelpfull: Yes(6) No(0)
- 325% of Z
30% of (X+Y)=?
30% of X = Y
Y+30% of Y=?
40% of Y = Z
130%=325% of Z - 6 years agoHelpfull: Yes(0) No(4)
