Question

Find a number whose fifth part is increased by 30 equal to its fourth part decreasd by 50​

Answer 1

Answer:

Step-by-step explanation:

Let the no. be x

So

x / 5 +30 = x / 4 -30

30 + 30 = x / 4 - x / 5

60 = x / 20

x = 60 * 20 = 1200

Answer 2

Answer:

1600

Step-by-step explanation

Let the number =x

x/5 + 30 = x/4 - 50

30 + 50 = x/4 - x/5

TAKE ALL x TERMS TO ONE SIDE

80 =( 5x - 4x ) / 20 (Take LCM of 4 and 5)

80 = x/20

CROSS MULTIPLY ;

x = 80*20

x = 1600
