Multiply Ratios by (2,3,3 LCM) i.e., 6x 
Total Capital of Chandra in 1 year = 9x × 3 + 4.5x × 9 = 27x+40.5x = 67.5x Total Capital of Shekhar in 1 year = 4x × 12 = 48x Total Capital of Azad in 1 year = 8x × 12 = 96x 
According to the question 67.5 + 48x + 96x = 12690 211.5x = 12690 x = 12690/211.5 = 60 Hence, Share of Chandra = 67.5 × 60 = 4050
