A shopkeeper sold $$12.750$$ kg of sugar one a day. On the next day he sold $$38.250$$ kg of sugar. On the third day he sold $$50.500$$ kg of sugar. How much of sugar in all did the shopkeeper sell altogether?

$$202.5$$ kg
0%
$$102.5$$ kg
0%
$$101.5$$ kg
Explanation
Sugar sold by the shopkeeper on the first day = $$12.750 \ \ kg$$
Sugar sold by the shopkeeper on the second day = $$38.250 \ \ kg$$
Sugar sold by the shopkeeper on the third day = $$50.500 \ \ kg$$
Hence the shopkeeper sold = $$(12. 750 + 38. 250 + 50.500) \ \ \ kg = 101.5 \ \ kg$$
Simplified value for $$12.500 + 8.75 + 2.25$$ is

$$13600$$
0%
$$23.050$$
Explanation
Given that we have to find the sum of three numbers
$$ 12.500 , 8.75 , 2.25 $$
$$8.75+2.25 = 11.00$$
$$12.500+8.75+2.25 = 12.500+11.000 = 23.500$$
So Option $$A$$
is correct

0.88
Explanation
The given decimals are $$0.8$$ and $$0.9$$
$$\Rightarrow$$ Difference between decimals $$=0.9 - 0.8 = 0.1$$
Now line is divided in $$5$$ equal segments.
Value of each segment is:
$$\Rightarrow$$ $$ 0.1 \div 5 = \dfrac{0.1}{5}=0.02$$
$$y$$ is placed at $$3rd$$ segment from $$0.8$$.
$$\therefore$$ Value of $$y$$
$$=0.8+0.02+0.02+0.02 = 0.86$$

Explanation
We know that to add numbers with different decimal places we expand all the numbers to the same decimal places by expanding zeroes.
So, the sum of 0.5 ,12.56 and 0.003
is
0.500+12.560+0.003 =13.063
Hence, the answer is 13.063
So, option A is the correct answer.
