The company owns seventy two buses at present....72<br /><br />The company owns seventy two buses at present.<br /><br />Let us assume that they have B buses right now and S space before the expansion. Now the space is enough for<br />S = B - 12 ----- [1]<br /><br />When they expand, they will have more space which will be enough for<br />S + 0.4 x S = B + 12 ------ [2]<br />=> 1.45 = B + 12<br />Also, B = 1.45 - 12 ----- [3]<br /><br />Now we can rewrite the equation [1] as<br />B = S + 12 ----- [4]<br /><br />Equating the third and fourth equation, we get<br />1.4 S - 12 = S + 12<br /><br />Subtract S from both sides<br />0.4 S - 12 = 12<br /><br />Now add 12 to both sides<br />0.4 S = 24<br /><br />Multiply by ten and divide by four on both sides<br />S = 60<br /><br />Put the value in fourth equation<br />B = 72<br />Adminnoreply@blogger.comtag:blogger.com,1999:blog-2893315201359920156.post-45740092292718968102014-12-11T17:46:50.306+05:302014-12-11T17:46:50.306+05:307272Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-2893315201359920156.post-4411369519625469262014-12-11T16:40:08.820+05:302014-12-11T16:40:08.820+05:30No, 60 4 old No, 60 4 old Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-2893315201359920156.post-17803348070458041122014-12-11T16:20:21.337+05:302014-12-11T16:20:21.337+05:3060 is answer..suppose it has 100 bus now. increasi...60 is answer..suppose it has 100 bus now. increasing it by 40% is 140..so for 1 bus it wil be 100/40=2.5 then for 24 buses it will be 2.5 *24= 60 bus Abhilash1000https://www.blogger.com/profile/13841324039973683529noreply@blogger.comtag:blogger.com,1999:blog-2893315201359920156.post-68085037988202025432014-12-11T16:13:41.808+05:302014-12-11T16:13:41.808+05:30those who put 72 as ans ,explainthose who put 72 as ans ,explainAnonymousnoreply@blogger.comtag:blogger.com,1999:blog-2893315201359920156.post-176247599715285992014-12-11T15:52:41.944+05:302014-12-11T15:52:41.944+05:307272Anonymoushttps://www.blogger.com/profile/15195490595538531492noreply@blogger.comtag:blogger.com,1999:blog-2893315201359920156.post-25198567102542908272014-12-11T15:43:34.046+05:302014-12-11T15:43:34.046+05:3040% of x = 24, x= 60, new = 60+24 = 8440% of x = 24, x= 60, new = 60+24 = 84Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-2893315201359920156.post-84098782118579081582014-12-11T15:40:37.911+05:302014-12-11T15:40:37.911+05:30At present company owns 72 busesAt present company owns 72 busesAnonymousnoreply@blogger.comtag:blogger.com,1999:blog-2893315201359920156.post-64368551796108438652014-12-11T12:44:30.638+05:302014-12-11T12:44:30.638+05:3084 is the answer ....ez question84 is the answer ....ez questionAnonymousnoreply@blogger.comtag:blogger.com,1999:blog-2893315201359920156.post-65020490721487920702014-12-11T00:38:25.736+05:302014-12-11T00:38:25.736+05:30The current capicity of the parking lot is 60 buse...The current capicity of the parking lot is 60 buses and 12 are parked outside thus the company has 72 buses.
