After giving,
Pebbles that Yong has = 1u + 26 - 55
= 1u - 29
Pebbles that Fitria has = 1u + 55
Difference = 84 pebbles
Since Fitria has 3 times as many pebbles now, this means Fitria has 2 times more pebbles = 84
84 ÷ 2 = 42
42 x 3 = 126
Fitria has 126 pebbles now.
126 - 55 = 71
Fitria had 71 pebbles at first.
Think of it this way:
Pebbles Yong now has → 1 part.
Fitria now has 3 times as many pebbles as Yong → 3 parts
Difference = 2 parts
So Fitria now has 2 times more pebbles than Yong
