Problem 10: Find a number which after being multiplied by 5 will exceed 60 as much as it is now short of 60.
a. 10 b. 15 c. 25. d.20
— number math —
Solution:
Let the number is ‘y’ and if we add ‘z’ it will become equal to 60 (we supposing it is ‘z’ less than 60)
i-e we suppose;
Now five time of the number;
Five times of number exceeds 60 by ‘z’
Com pairing eq 1 & 2
So, the number is 20
Check
Number =20
Short of 60=60-20 = 40
i-e it is 40 less than 60
Now five times of number = 5×20=100
Excess more than 60 =100-60=40
Thus it is 40 more than 60 and meets the condition of the problem
