`3frac{1}{5} + 1frac{2}{3}` is equal to

Add the following: 3frac{1}{13} + 1frac{4}{13} + 2frac{3}{13}

If reflection of A(1, -10, 1) about the line frac{x-1}{2} = frac{y-1}{3}=frac{z-2}{5} is (alpha, beta, gamma) then the |2 alpha 3 beta 5 gamma| is

If the shortest distance between the lines frac{x - lambda} {-2} = frac{y - 2} {1} = frac{z - 1} {1} and frac{x - sqrt 3}{1} = frac{y-1}{-2} = frac{z-2}{1} is 1, then the sum of all possible values of lambda is :

1 + frac(1)(2) + frac(1) (4) + frac(1)(7) + frac(1)(14) + frac(1)(28) is equal to

Let (alpha, beta, gamma) be the foot of perpendicular from the point (1, 2, 3,) on the line frac{x 3}{5} = frac{y - 1}{2} = frac{z 4}{3} then 19 (alpha beta gamma)

If x and y are positive with x-y=2 and xy=24, then frac(1)(x) + frac(1)(y) is equal to

(frac(1) (216))^(frac(2)(3)) div (frac(1)(27))^(frac(4)(3)) is equal to (A) frac(3)(4) (B) frac(2)(3) (C ) frac(4)(9) (D) frac(1)(8)

((3frac{1}{3}-2frac{1}{2})div 1/4 of 1frac{1}{4})/(10+6 xx 3) of 4/15 div ((1/3div1/3 of 1/9)/(9 xx 3div6))

The sum of two numbers x & y is 36 and Their HCF and LCM are 3 and 105 respectively. then frac(1)(x)+frac(1)(y) is equal to (A) 35 (B) frac(3)(5) (C) frac(4)(35) (D) frac(1)(35)
