Puzzle 3: In a class test Tony scored 160 marks
in Geography and History together. If one third of his marks in Geography
equals to half of the marks he scored in History, then how much has he scored
in History?
Answer: 64
Explanation: Let the marks in Geography be G and
History be H.
Eq 1: G + H = 160
Eq 2: G/3 = H/2
By the problem:
G = 160 - H
Therefore, putting the value of G in Eq 2:
(160 - H)/3 = H/2
Or, 320 - 2H = 3H
Or, 3H + 2H = 320
Or, 5H = 320
Or, H = 64
