Question

add fifty to 7 times a number . the some is 40 less than triple century . Find the number

Answer 1

Answer:

30

Step-by-step explanation:

Let us assume the number be x.

Take me seven times over and add a fifty = 7x+50

To reach a triple century you still need forty = (7x + 50) + 40 = 300

= 7x + 50 + 40 = 300

= 7x + 90 = 300

By Transposing 90 from LHS to RHS it becomes -90

= 7x = 300 – 9th

= 7x = 210

Divide both side by 7

= 7x/7 = 210/7

= x = 30

x = 30Hence the Number is 30.
