you are correct...without the knowledge of good mathematics.....you can't solve this problem........
You need always knowledge of a subject to solve a problem though you also need intelligence Similar questions may be raised in Economics, statistics, Geography. Mere intelligence will not help.
Actually intelligence quotient is a psychological term. This is calculated by formula- M.A./ C.A. Thus if a child is ten years old but the mental development is that of five years old, the IQ is .5.
