Step-by-step explanation:
bye bye!
Answer:
Then, X - 8 % = 69. 100x - 8 = 69. 100x =100 = 2/25 (div. By 4)]
x−2x/25=69
(25x - 2x)/25 = 69
23x/25 = 69
23x = 69 * 25
x = (69*25)/23 [as 69 / 23 = 3,]
x = 3 * 25
x = 75
Step-by-step explanation:
A number when decreased by 8% gives 69
So, 69 = 100–8=92% of the number
If, 92% of the number = 69
1 % of the number= 69/92
100%of the number= (69/92)*100 = 75
ANOTHER METHOD
Let the number be x
By the problem,
x - 8x/100 = 69
or, (100x–8x)/100 = 69
or, 92x= (69*100)
or, x = (69*100)/92 = 75
Ans: the number is 75
original value. Now it is decreased by 8% ; so the new value is (100— 8)% or 92% of n
So,. 92%of n = 69
Or, 92/100× n = 69
n = 69× 100/92 = 75
The original number was 75
So,. 92%of n = 69
Or, 92/100× n = 69
n = 69× 100/92 = 75
The original number was 75
