1.26 is the single decimal multiplier.
Step-by-step explanation:
Let a number be x.
If x is increased by 5% then the value of the number is( (100+5) /100) ×x=1.05x
Again if 1.05x is increased by 20% then the value of the number=((100+20) /100) ×1.05x = 1.2×1.05x=1.26x
Thus it is found that single decimal multiplier used for successive increase of 5% and 20% is 1.26
