Match the following.
|(i) For any two integers
a and b, a × b
is also an integer.
Thus, integers are
|(A) Distributive under addition
|(ii) a × b = b × a; this denotes
that integers are
|(B) Positive quotient|
|(iii) a × (b + c) = a × b + a × c; this
denotes that integers are
|(C) Closed under
|(iv) The division of a negative
integer by another negative
integer results in
|(D) Commutative under
A (i) → (B), (ii) → (C), (iii) → (D), (iv) → (A)
B (i) → (C), (ii) → (D), (iii) → (A), (iv) → (B)
C (i) → (D), (ii) → (C), (iii) → (A), (iv) → (B)
D (i) → (C), (ii) → (D), (iii) → (B), (iv) → (A)
The bar graph given below shows the weights of a beaker when empty and when different balls are placed in it.
How much heavier is ball C than ball B ?
I can't make out the values properly, the graph is unclear
The figure shows the amount of water in 3 beakers at first. Karan poured 150 mL of water from beaker P to beaker Q. He then poured 200 mL of water from beaker Q to beaker R. Finally, he poured 100 mL of water from beaker R to beaker P. Which one of the following statements is true?
ABeaker P contained more water than the other beakers at the end.
BBeaker Q contained more water than the other beakers at the end.
CBeaker R contained more water than the other beakers at the end.
DThe three beakers contained the same amount of water at the end.
