Let the number be x.
From the condition,
X x 63/100 - X -45/100 = 34.2
63x/100 - 45x/100 = 34.2
18x/100 = 34.2
18x = 34.2 x 100
18x = 3420
x = 3420/18
x = 190
Therefore,
78% of x = 78/100 x 190
= 148.2
From the condition,
X x 63/100 - X -45/100 = 34.2
63x/100 - 45x/100 = 34.2
18x/100 = 34.2
18x = 34.2 x 100
18x = 3420
x = 3420/18
x = 190
Therefore,
78% of x = 78/100 x 190
= 148.2
