Question
In how many ways can the letters of the word PARALLEL be
arranged so that all the L's do not come together?Solution
Total letter in word PARALLEL =8 L=3times A=2times 
If all L are considered as one, then the number of letters is -6. A=2times Total ways of L come together =6! /2! =6×5×4×3=360 Now total ways of L's do not come together=3360-360 =3000
Given a triangle with two sides measuring 12 cm and 16 cm, which of the following cannot be a possible length for the third side?
- Find the remainder on dividing (5x 3  + 4x 2  – 10x + 1) by (2x – 4).
The area (in sq, units) of the triangle formed by the graphs of 8x + 3y = 24, 2x+8 = y and the x – axis is:
If x −y =4and xy =45,thenthevalueof x 3 −y3is:
If x + y = 2 and 1/x + 1/y = 18/15, then find the value of (x3 + y3)?
22% of ‘x’ is equal to 66% of ‘y’, then find the value of x: y.
If y + 1/y = 2 then find y117 + 1/(y117)
if a2 + b2 + c2Â =Â 2(4a -5b -9c)-122 , then a-b-c = ?
If a – b – c = 0, then the value of (a2 + b2 + c2)/(b + ac) is:
If 5x - 13xy + 6y = 0, find x : y.
