Question
Diamond-water paradox establishes the fact that
Solution
The paradox of value (also known as the diamond–water paradox) is the contradiction that, although water is on the whole more useful, in terms of survival, than diamonds, diamonds command a higher price in the market. Marginal utility, not total utility, is the critical determinant of price. The price of water is relatively low because the marginal utility is relatively low.
120% of 25 + 80 X 2 = ?2 - 6
115% of 40 + 3 × 4 = ? × 11 – 8
20 + 160/? × 20 = 420
56 × 18 + ? × 21 – 49 × 12 = 63 × 26Â
1220 ÷ 61 ÷ 5 + 450 of 20% - 70 = √ ?
What will come in the place of question mark (?) in the given expression?
7 X 18 + ? = (52 - 6) X 9
13/3 – (23/6) = ? – (22/9)
4.2 × 6.5 × 7.8 = ?
Determine the value of ‘x’ if x% of 500 plus {1250 ÷ x of 10} × 5 equals 130
