How total is 47?

In a row, Radha is 17th from the left end. Pintu is 24th from the right end of the row when they interchange their positions. Pintu becomes 31st from the right. Find (i) Total



Total is 47.

I didn't understand this position type problem.

When they swap position, Pintu is both 31st from the right and 17th from the left, so there are 47 positions.

We can't able to know in between members. How can you total it?

As there is a position that is both 17th from the left end (where the left end is position 1) and 31st from the right end, the number of positions is 17 + 31 - 1 = 47.

After interchanging; Radha is 24th from the right end; 47 – 24 + 1 = 22th from Left side?

47 - 24 + 1 = 24

For 47 positions, the 24th position from the right end is also the 24th position from the left end.
