Step-by-step explanation:
✬ Number = 672 ✬
Explanation:
Given:
One seventh of a number exceeds one eighth of the number by 12.
To Find:
What is the number ?
Solution: Let the number be x. Therefore,
➟ 1/7th part of x = 1/7 × x = x/7
➟ 1/8th part of x = 1/8 × x = x/8
A/q
Ones seventh part exceeds one eighth part by 12
1/7th part = 1/8th part + 12
Hence, our equation will be
x/7 = x/8 + 12
x/7 = (x + 96)/8
8 × x = 7 × (x + 96)
8x = 7x + 672
8x – 7x = 672
x = 672
Hence, the number she thought was 672.
[ Verification ]
Seventh part = 672/7 = 96
Eighth part = 672/8 = 84
Difference = 96 – 84 = 12
