Answer 1

Let's take x for one cookie then we'll get,
X + X + X = 30
3X = 30
X = 10

Let's take y for one banana then we get
Y + Y + Y + Y + 10 = 14
4Y = 4
Y = 1

Let's take Z for one clock then we get,
2 + Z + Z = 8
2Z = 6
Z = 3

=>Now in the last one when we OBSERVE properly we find that,
1)Earlier the both the clocks showed 3 and the value for each was also 3 but now the clock shows 2 so the value will be 2.
2)There is only one banana now.
3)Earlier there were 10 brown dots in cookies and the value was also 10 but now there are only seven so the value will be seven.

Now, apply BODMAS
2 + 1 + 1 x 7 = 2 + 1 +7 = 2 + 8 = 10.

NOTE: You just need to have good observation power.

Thanks.
Hope this was expected!!!
