In his wardrobe, Timothy has three trousers. One of them is black, the second is blue and the third is brown. He also has 4 shirts. One of them is black and the other three are white. He opens his wardrobe in the dark and picks up one shirt-trouser pair without examining the colour. What is the likelihood that both the shirt as well as the trouser are black?

I. all are divisible by 55,
II. the difference between the digits in the hundred's and ten's place is one more than the digit in the unit's place?
A triangle ABC has 2 points marked on side BC, 5 points marked on side CA and 3 points marked on side AB. None of these marked points is coincident with the vertices of the triangle ABC. All possible triangles are constructed taking any three of these points and the points A, B, C as the vertices. How many new triangles have at least one vertex common with the triangle ABC?
a 256
b 237
c 207
d 127

Bhai logo ek baat clear karna.. Greatest integerer function ka nd least integer function ka.. For greatest integer function according to graph ny value lying between eg 1 & 2 will go down to the previous integer i.e. [1.5]=1 nd [-1.5]=-2.. Exactly opposite will be the case for least integer function. BDW grestest integer function is the ceiling function nd least integer is floor?
A driver of an auto-rickshaw makes a profit of 20% on every trip when he carries 3 passengers and the price of petrol is Rs. 30 a litre.

pls explain your approach. My ans is not matching with the oa
Bhai logo ek baat aur clear karna.. jab hum number of digits nikalte h.. Toh N=18^5 h lets say.. dono side log lete h.. fir LogN=5 log 18= isko solve karke lets say aaya 6.27 so answer will be 6 rite. 6.57 aye toh bhi 6.. In case of number of zeros after decimal.. let say N=-168.0456 so answer will be -168.. Answer -168.59 aye toh bhi -168.. Rite??
