Question

(a) 180 (b) 75
(c) 150
(d) 300
​

Answer 1

Answer:

Step-by-step explanation:

Percentage you may be knowing %............

75% of A = (75/100)*A.......

Similarly, others..............

So according to question :

(75/100)*A = (25/100)*B

So, 3A = B..... (1)

And,

B = (x/100)*A........ (2)

From (1) & (2):

3A = (x/100)A

So, x=300.......
