Answer 1

Answer:

his monthly salary is rupees 60,000

Step-by-step explanation:

Let the monthly salary be x

we will first add all his fractions and the left over money and then equate to x

1/5 of x + 1/4 of x+ 1/3 of x + 1/15 of x +9000 = x

we will now take lcm

12x + 15x +20x + 4x/60 +9000 = x

51/60x + 9000 = x

9000 = x - 51/60x

9000 = 60-51/60x

9000 = 9/60x

9000 * 60 = 9x

9000 * 60 / 9 = x

60,000 rupees
