47?(3 + 5) * 4 + (5) * 3 = 47

: ur logic??

Each person from X can fight every person from Y and Z.
So 8 fights per person.
Total fights involving employees from X = 8 *4 = 32

Each person from Y can fight every person from X (already calculated) and Z.
So 5 fights per person (with Z).
Total fights between Y and Z = 5 * 3 = 15

Total = 32 + 15 = 47

OA for previous one- 47

a and b are two vectors and the angle between a and b is θ. If (a + 3b). (7a – 5b) = 0 and (a – 4 b). (7a – 2b) = 0, then the value of tan θ is

θ = tan -1 (root3 / 2) ? :P

pata nahi...got b = 2a.

Then hypotenuse daal diya from a to b..Bhool gaya sab physics :|

my logic : lets convert everything in g and cmso let side of cube =x now vol of water displaced when no mass on it =x^2*(x-2)(soo this + 0.2Kg )*density of water =vol of cubeso since were takin everything in g/cm^3, denstiy of water =1we get:x^3=200+x^3-2x^2solve u get x=10

bhai hamne bhi toh yehi kiya tha....

option B ?

[messy_19]

All three are correct.

triangle PQS ~ RQP ~ RPS.

And the angles Q and R are congruent, so all are correct.

u said b is the answer that means u feel they r congruent na

[messy_19]

Angles Q and R congruent hai. So SAA theorem se ho jaega na bhai?
