The sum of 70 + 30 + 1250 + 50 + 100 = 1500
If you have 70% of something and 30% of another identical "something" that is equivalent to 50% of the two "somethings".
362. Next time, just use a calculator.
70 + 80 + 70 + 30+ 80 + 80+ 80 = 490
If you have two pairs of numbers whose sum is the same, their product increases as the two numbers get nearer to half the sum. The product is a maximum at that value. 70 * 30 = (50+20)*(50-20) The right hand side is the factorisation of the difference of two squares, and can be shown to be equal to 502 - 202 Since 202 must be positive (it is a square), 70*30 must be less. For all values of x, (50+x)*(50-x) is less than or equal to 50*50=2500 with equality attained only when x = 0.
70 + 70 + 50 + 50 = 240
