Solution(By Examveda Team)
Let there be n rows, then number of trees in each row = (n + 1) Thus, total number of trees, n × (n +1) = 5550 Now, at this moment this problem can be solved in two ways. First by finding the roots of quadratic equation. Second, by using the values from options. 74 × 75 = 5550 i.e. (n + 1) = 75Related Questions on Number System
