Re: Oral puzzles
Hi bobbym,
The solution I get to 995 : First number = 125 and second number = 40.
One fifth of 125 = 25 and 5/8 of another number = 5/8 x 40 = 25.
Similarly, 35 + 125 = 160 and four times the second number = 160.
Continuing.....
#996. The average of four consecutive even numbers is 27. Find the largest of these numbers.
