Every number is one of the forms 5n, 5n pm 1, 5n pm 2 .

The shortest distance between the line L_1=(hat i - hat j hat k) lambda (2 hat i - 14 hat j 5 hat k) and L_2=(hat j hat k) mu (-2 hat i - 4 hat 7 hat) then L_1 and L_2 is

Let L_1 :x+y-3= 0 and L_2:7x -y +5 = 0 be two given lines. Let image of every point on L_1, with respect to a line L lies on L_2 then possible equation of L can be :

Five balls L1, L2, L3, L4 and L5 are kept one above the other (not necessarily in the same order). L1 is just above L5 and just below L4. L2 is just above L3 and just below L5. How many balls are above L2? पांच गेंदों L1, L2, L3, L4 और L5 को एक के ऊपर एक रखा जाता है (जरूरी नहीं कि उसी क्रम में)। L1, L5 के ठीक ऊपर और L4 के ठीक नीचे है। L2, L3 के ठीक ऊपर और L5 के ठीक नीचे है। L2 के ऊपर कितनी गेंदें हैं?

Equation of a line segment in first quadrant is given as 4x+5y=20 , two lines l_1 , and l_2 are trisecting given line segment. If l_1 and l_2 pass through the origin the find then tangent of angle between l_1 , and l_2 .
