Explanation

20% of 781 is approx 156. 40% of 89 is approx 36. 156 + ? + 36 = 252. 192 + ? = 252. ? = 60.

AI explanation

Rounding the numbers allows us to estimate 20% of 780 as 156 and 40% of 90 as 36. Substituting these values into the original equation results in 156 plus the unknown plus 36 equals 252. Combining the known terms gives 192 plus the unknown equals 252, so subtracting 192 from 252 reveals the missing value is 60.
