Question 158
The average height of 27 persons was recorded as 162 cm. If the height of Shreyas was deleted from the observation, the average height reduced by 1 cm. What was Shreyas’ height?
Solution
Let Shreyas's height be 'x' cm.
Since, Average decreases by 1 cm,
$$\frac{27\times162-x}{26}=161$$.
$$x=162+26=188 cm$$.
Hence, Option E is correct.
