Question

Divide 80 into two parts such that one part is 3 times the other.

Answer 1

Answer:

20 and 60

Step-by-step explanation:

Let one part be x so according to the given condition, the second part becomes 3x.

Since the sum of both the parts must be 80,

x + 3x = 80

4x = 80

x = 80/4

x = 20

Therefore one part is x = 20

and the other one is 3x = 3×20 = 60

Answer 2

Answer:

Let the first no be x

and the second no be 3x .....................................(1 eq)

total no is 80

3x + x =80

4x =80

x = 80÷4

x = 20

from 1 eq we get 3x

3*20 (as x = 20)

60

first no is 20

and second no is 60..
