In a row of girls facing North, Tanu is `10^(th)` to the left of Priyanks, who is `21^(st)` from the right end. If Twinkle, which is `17^(th)` from the left end, is `4^(th)` to the right of Tanu, how many girls are there in the row?

Options

A. Data inadequate
B. 43
C. 44
D. None of these

Answer

B

Explanation

Priyanka.s rank from the right end `=21^(st)` Tanu.s rank from the left end `=13^(th)`. Twinkle.s rank from the left end =`17^(th)`. Twinkle.s rank from the right end = `(21+6)= 27^(th)`

So, total number of girls in the given row `=(17+27)-1= 43`
Another way: Priyanka.s rank from the left and `=(13+10)= 23^(rd)`. Total number of girls in the given row `=(23+ 21)-1 = 43`.
