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.
