12- a option???
Plz ignore this
What is the answer for 11th
Iam getting b) for 11th..
It follows a pattern (-1+-1+8) for every three consecutive terms.
So we get sum till 99 th term as(6*33)=198.
The last term is -1 so ans is 197 ..
If anything wrong pls correct me.
The answer is b for 11 th question ..Thank you for the help...can you please show the solution of question 12?
use traingle inequality
|a+b|=|a|+|b| according to equality hold condition...
Can anyone explain me ques 12
For 12th i think the question should be
| 2z1 + 3z2 + 2z3 | instead of 12z1
If it is so , then I’m getting option D i.e 1
@Sneha_2021 don’t you think , that for the required value to be 7 , the argument of all the 3 numbers would have to be same , and then that would violate the condition given in the question
Sir answer is D option ,i have also that book
