Then X/7 – x/11 =100 11x-7x = 7700 x=1925.<br /><br />2) The ratio of Rita’s age to her mother’s age is 3:8. The difference of their ages is 35 years. The ratio of their ages after 4 years will be:<br />(i) 7:12<br />(ii) 5:12<br />(iii) 38:43<br />(iv) 42:47<br />Solution:<br />Let their ages be 3x and 8x<br />8x – 3x =35<br />x =7<br />Their present ages are 21 and 56 years.<br />Ratio of their ages after 4 years are 25:60 = 5:12<br /><br />3) Gold is 19 times as heavy as water and copper is 9 times as heavy as water. In what ratio should these be mixed to get an alloy 15 times as heavy as water?<br />(i) 1:1<br />(ii) 2:3<br />(iii) 1:2<br />(iv) 3:2<br />Solution:<br />Let 1gm of gold be mixed with x gm of copper to give (1+x)gm of the alloy.<br />1G=19W, 1C = 9W and alloy = 15W 1gm gold + x<br /><br />4) A tap can fill the tank in 15 minutes and another can empty it in 8 minutes. If the tank is already half full and both the taps are opened together, the tank will be:<br />(i) filled in 12 min<br />(ii) emptied in 12 min<br />(iii) filled in 8 min<br />(iv) emptied in 8 min<br />Solution:<br />Rate of waste pipe being more the tank will be emptied when both taps are opened.<br />Net emptying workdone in 1min =(1/8 -1/16)= 1/16<br />So full tank will be emptied in 16 min<br />Half tank will be emptied in 8 minutes.<br /><br />5) What is not a part of OS ?<br />a)swapper<br />b)compiler<br />c)device driver<br />d)file system<br />Answer is compiler<br /><br />6) Which is the protocol used by PING?<br />a)ICMP<br />b)HTTP<br />c)SMTP<br />d)RTSP<br /><br />Answer is ICMP<br />7) Hotmail was founded by?<br />a)Sabeer Bhatia and Jack Smith<br />b)Sabeer Bhatia alone<br />c)Sabeer Bhatia and Bill Gates<br />d)Sabeer Bhatia and Hang Sen<br />Answer is Sabeer Bhatia and Jack Smith<br /><br />8) Which is an Internet standard that extends the format of e-mail to support<br />* non ASCII text<br />* Non-text attachments<br />* Message bodies with multiple parts<br />* Header information in non-ASCII character sets<br />a)Multipurpose Internet Mail Extensions<br />b)Multivariant Internet Mail Extensions<br />c)Multi Internet Mail Extensions<br />d)None of the above<br />Answer is Multipurpose Internet Mail Extensions<br /><br />9) An application program that is used by the users to get the information from the backend of some application like databases.<br />a)application server<br />b)database server<br />c)proxy server<br />d)mail server<br />Answer is database server<br /><br />10) Why is the synchronize used?<br />a)to initialize multiple objects<br />b)to lock an object<br />c)to release an object<br />Answer is to lock an object<br /><br />11) IRC stands for<br />a)Intranet Relay chat<br />b)Internet Relay chat<br />c)Intranet subnet Relay chat<br />Answer is Internet Relay chat<br /><br />12) VPN stands for<br />a)Virtual private network<br />b)Virtual public network<br />c)Virtual path network<br />Answer is Virtual private network<br /><br />13) Four persons A, B, C and D are playing cards.

Her age is between 50 and 70.Each of her sons have as<br />many sons as they have brothers. Their combined number gives Lucia’s age. What is the age?<br />ANSWER<br />Let the no. of Lucia’s sons = n<br />No. of brothers for each son = n-1<br />No. of sons for each of Lucia’s son = n-1<br />Lucia’s age = n-1 * n-1<br />= a perfect square between 50 and 70<br />= 64</div>iqs pdfhttps://plus.google.com/114623642748522820843noreply@blogger.com
