Answer:1200
Step-by-step explanation: Let the no. be x
x/5+30=x/4-30
or, 30+30=x/5-x/4 (Transporting 30&x/5 to LHS&RHS respectively)
or, 60=x/20
or,x=60×20 (Transporting 20 to LHS)
=1200

Answer:
1200
Step by step explanation: haiii!!!
let the number be x
so, according to the question the equation becomes :
x/5 + 30 = x/4 - 30
by taking lcm on both sides and cross multiplying we get,
- 4(x+150) = 5(x-120)
- 4x + 600 = 5x - 600
- 600 + 600 = 5x - 4x
- x = 1200
