Question

find a number whose fifth part increased by 30 equal to its fourth part decreased by 30​

Answer 1

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
