Answer:
product of a and b=480
Step-by-step explanation:
Let two numbers are a and b. Their average is = 22
Average = sum of numbers / total numbers
22 = a +b /2
a+ b = 22*2=44
60% of a = 50% of b
60a/100 = 50b/100
60a = 50 b
a = 50b/60= 5b/6
5b/6+b = 44
5b +6b /6 = 44 (taking 6 as lcm)
11b/6 = 44
b = 44*6/11
b= 4*6 = 24
So, a = 44–24 = 20
product of a and b = 20*24 = 480
