Let the numbers be x, x + 2, x + 4, x + 6, x + 8 and x + 10.
Given (x + 2) + (x + 10) = 24 => 2x + 12 = 24 => x = 6 The fourth number = x + 6 = 6 + 6 = 12.
Total Students = X
Fail Student = 45% of X
Pass Student= 550
X x 45% of X = 550
X value is one so 45% of x means .45 so we less one from .45
1 - .55 = 550
X = 550/.55
X = 55000/55
X =1000
Average Age of Iqra, Rashida and Rizwana
= (17+16+12)/ 3
= 45/3
Average Age =15
Increase Age After added Ali = 5 x 4 =20 years
15+20 = 35
Ali age = 35
