Q1. In a row of children, Geeta is fifth from the left and Praveen is twelfth from the right end. If Praveen shifts three places towards Geeta, he becomes tenth from the left end. How many children are there in the row?
A 20
B 22
C 24 Correct
D 26
Explanation
After shifting three places towards Geeta, Praveen is tenth from the left. Since he moved towards Geeta, who is on the left side, his original position was three places to the right of tenth, that is thirteenth from the left. He is also twelfth from the right. Total children in a row equal left position plus right position minus one: 13 + 12 - 1 = 24. The counts 20 and 22 are too small for these two end positions, while 26 would place Praveen farther from one end than stated.
