Question

In a row Ram is 17th from the left end and

Raj is 15th from the right end, if they interchange

their positions Raj will be in 25th position from

the right end, and then find the total number of

persons in the row?​

Answer 1

Answer:

if we take total no of persons =x

then,

after interchanging ram posn will become raj and raj posn will become ram's

therfore

posn of raj = posn of ram

and posn of raj is given from the right end so first we have to convert it into left end

it will be (x+1)-25

now,

(x+1)-25=17

therfore value of x will be 41

hence total no. of person =41
