Class : Class 1

The correct answer is B.

Quantity of flour Beena had = 4 kg = 4000 g
Quantity of flour used to bake cake = 3 kg 60 g = 3060 g
Quantity of flour left with Beena = 4000 – 3060 = 940 g
Hence, the right answer is Option B.

## Ans 2:

Option a. A is cooler than B because if you draw a number line,-4 is less than -1. When we go to the left it is decreasing and when it goes to right, it is ascending. Regards, class 6 boy Can't tell my name.

## Ans 4:

Class : Class 7
since, (-4) lies left to (-1) on a number line.so, -4< -1.: A is cooler than B

## Ans 2:

Class : Class 6
If we take a as 4 and b as 2, then according to communicative property, 4-2=2 but 2-4=-2 so 2 and -2 are not equal but, if we take a as 4 and b as 4, then it will be 4-4=0 and 4-4=0. Thus, a should be = b
