If 4% of (A + B) is equal to 28% of (A – B), then find A : B.
If 4% of (A + B) is equal to 28% of (A – B), then find A : B.
यदि (A +B) का 4%, (A – B) के 28% के बराबर है, तो A : B ज्ञात कीजिए।
Detailed Solution & Logic
Correct Answer:
4 : 3
0.04(A + B) = 0.28(A - B)
4(A + B) = 28(A - B) multiply both sides by 100
4A + 4B = 28A - 28B
4B + 28B = 28A - 4A
32B = 24A
$ \frac{A}{B} = \frac{32}{24} = \frac{4}{3} $
A : B = 4 : 3
