Answer 1

Answer:

Q.31Probabilities are if

X=4,Then Y=6 Then Z=10

Therefore

4+6-10/4-6+10=0/8

=0(You can try with other numbers as well but always answer will be 0)

Q.32 Given ratio of two numbers 5:9

if 9 is added to each the new ratio is 16:27

Now suppose X is multiplied by old ratio

=>5x+9/9x+9=16/27

=>27(5x+9)=16(9x+9)

=>135x+243=144x+144

=>243-144=144x-135x

=>99=9x

=>X=99/9

=>11

So their present ages are

5x11=55 years

9×11=99 years

So correct answer is 99 years
