(a) 60
(b) 65
(c) 75
(d) 105

​

Answer 1

Answer:

let the number be x

then acocording to question,

35% of x +39 = x

35/100 × x + 39 = x

(after cancellation )

7/20x + 39 = x

(7x + 780)/20 = x

7x + 780 = 20x

780 = 20x -7x

780 = 13x

780/13 = x

60=x

therefore option a is correct

Answer 2

Answer:

Suppose, that number be x.

So as per condition, x × 35/100 + 39= x

or, x - 35x/100 = 39

or, 65x= 3900

or, x= 3900/65=60.

Hence, required number is 60.
