Physical Geography: Location, Relief, Rivers and Climate
The Mahanadi rises in the Sihawa hills of which district of Chhattisgarh?
The Mahanadi’s source is near Sihawa (Nagri-Sihawa area) in Dhamtari district. It first flows north, then turns east into Odisha and reaches the Bay of Bengal. Kanker is a neighbouring district, which makes it a tempting distractor.
Basic Numeracy
The average of five numbers is 24. When one number is removed, the average of the remaining four numbers is 22. What is the number removed?
Sum of five numbers = \( 5 \times 24 = 120 \); sum of the remaining four = \( 4 \times 22 = 88 \). Removed number = \( 120 - 88 = 32 \).
