Answer:
252
Step-by-step explanation:
let x be the number
according to the question
3x. x×40
------- = ----------- + 12
7 100
3x 4x
----- = --------- + 12
7 10
3x 4x + 120
------- = -------------------
7 10
3x × 10 = 7(4x + 120)
30x = 28x + 840
30x-28x = 840
2x = 840
x= 420
now, 60% of x
x × 60 420 × 60
------------ = ----------------
100 100
= 42 × 6
= 252 ans.
