If 37 * 14 = 17, 69 * 33 = 34 and 91 * 125 = 72, then 75 * 66 = ?
Answer & explanation
Correct answer: option 3
The correct answer is Option (3) → 47
Find the rule from the three solved examples: add the two numbers and divide the sum by 3.
37 * 14: \(37+14=51\) and \(51\div3=17\)
69 * 33: \(69+33=102\) and \(102\div3=34\)
91 * 125: \(91+125=216\) and \(216\div3=72\)
The rule fits all three, so for 75 * 66: \(75+66=141\) and \(141\div3=47\)
