If a batsman scored 120 runs which included 9 boundaries and 3 sixes, then what percent of his total score did he make by running between the wickets?

If A : B = 3 : 2, then (3A – 2B): (2A – B) is equal to

If a =500, b=502 and c=504, then the value of a³ +b³ +c³-3abc

A train running at the speed of $${140\over 9} $$  m/sec, crosses a pole in 27 sec. Find the length of the train.

4⁶¹ + 4⁶² + 4⁶³ + 4⁶⁴ is divisible by: 

If $$ {y\over x-z}={y+x\over z}={x\over y}$$ the find x:y:z is?

If (a-b)=-3 , (b-c)=5 and (c-a)=-2, then the value of $$ {a^{3}+b^{3}+c^{3}-3abc\over a+b+c}$$.

If (x¹¹+1) is divided by (x+1), then the remainder is :
