(b) Ifx : y = (a - b): (a + b) and z: y = 3(a - b): 2(a + b), then
find
(4)
(c) If (x + y) is more than (x - y) by 40% of (x - y), then how much
percent of y is x?
(4)
X: Z.​

Answer 1

Answer:

200

Step-by-step explanation:

Let the share of Z be m

Then Y gets

100

120

×m=1.2m

And X gets

100

125

×1.2m=1.5m

Then, x+y+z gets 1.5m+1.2m+m=3.7m

But total share is Rs. 740

∴3.7m=740

⇒m=200
