5 =? =? 2? 2 = 169 = 13 2? = ? = ? = ? = ( + ) 67 67? = 49 + = ( ) = = = Substitute a and b values as '1' and solve all the equations. All A, B and C values will be same and D value will be different. 6. Sugar quantity is 30% of 16 = 4.8 Sugar quantity will be the same in the remaining solution as only water evaporates when boiled Required percentage of sugar is = 40% Let the number of articles purchased be 'x' = 1 x = 16 x x + 2

6 Shortcut: Solve the question by options ( TR 8. Amount = P 1 + ) 100 ( = P 1 + ) 100 P = = Rs.6, Shortcut: For one year, rate of interest is 6% and for 4 years it is 4 6% = 24%. Then the amount will become 124%. If 124% money is Rs.8,060, 100% money will be = Rs.6, Let the length of the second train be 'x' metres x = (69 35) x = x = = 110 Length of the second train is 110 m. 10. Total Parts = = = each part = = Their shares are 7 200, and , 1600 and 1200 If 200 is added to each of them then their shares will be 1600, 1800 and 1400 Their ratio = 1600 : 1800 : 1400 = 8 : 9 : ( ) : (5 + 20) 45 : 25 = 9 : = 120% 25
