Question

One fifth of a number, is 25 frame an equation and solve it​

Answer 1

Step-by-step explanation:

One-fifth of a number is equal to 5/8th of another number. If 35 is added to the first number, it becomes four times of the second number. What is the second number?

The second number is 40.

Allow the first number to be a and the second number will be b.

a5=5b8

⟹5×a5=5×5b8

→a=25b8

a+35=4b

⟹25b8+35=4b

⟹8(25b8+35)=4b×8

⟹(25b+280)−25b=32b−25b

⟹7b7=2807

b=40
