160 gm

Step-by-step explanation:

Mean = $\frac{\text{Sum of masses of apples}}{\text{No. of apples}}$

100 = $\frac{\text{Sum of masses of apples}}{3}$

$100 \times 3 = \text{Sum of masses of apples}$

$300 = \text{Sum of masses of apples}$

So, the mass of 3 apples is 300 gm.

Now we are given that the largest apple is removed , the mean mass of the remaining two apples is 70 grams

$\text{Mean mass of two apples}=\frac{\text{Sum of masses of two remaining apples}}{\text{No. of apples}}$

$70=\frac{\text{Sum of masses of two remaining apples}}{2}$

$70 \times 2=\frac{\text{Sum of masses of two remaining apples}}{2}$

$140=\text{Sum of masses of two remaining apples}$

So, mass of two apples is 140 gm

Total mass of 3 apples = 300 gm

So, mass of largest apple = 300 - 140 = 160 grams.

Hence the mass of the largest apple is 160 gm
