<td style="border-bottom:none; border-left:none; border-right:none; border-top:none; height:20px; vertical-align:bottom; white-space:normal; width:85px">The ratio 5:7 means total parts = 5+7 = 12. These 12 parts are equal to Rs. 72,000. So one part = 72000/12 = Rs. 6,000. B has 7 parts, so B's salary = 7×6000 = Rs. 42,000.</td>
