Middle term of average × Number of batsmen = [(40 + 44)/2] × 12 = 504
⇒ Middle term of average × Number of batsmen = [(44 + 48)/2] × 10 = 460
⇒ Middle term of average × Number of batsmen = [(48 + 52)/2] × 8 = 400
⇒ Middle term of average × Number of batsmen = [(52 + 56)/2] × 6 = 324
⇒ Middle term of average × Number of batsmen = [(56 + 60)/2] × 4 = 232
⇒ Mean =

504+460+400+324+232

12+10+8+6+4

=
