D) (i) and (ii), both are false.
Correct Answer: C
Solution :
Statement (i): \[2a+3b=2\,(-2)\,+3(5)\] \[=-4+15\] = 11 \[2b-a=2\times 5-(-2)\] \[=10+2\] \[=12\] \[a-b=-2-5\] \[=-7\] and \[{{a}^{2}}-{{b}^{2}}\,={{(-2)}^{2}}-{{(5)}^{2}}\] \[=4-25\] \[=-21\] \[{{a}^{2}}-{{b}^{2}}=-21\] is least value. Statement (ii): Anshi?s present age (16 + x) years After Z years, Anshi will be \[16+x+z\] years old.You need to login to perform this action.
