O yes, I didn't read properly. You r right. Therefore, 1u - 2.80 (A )18u - 18 × 2.80 7u - 7 × 2.80 Thanks, Evon Ong

Check back :- $2.80 + $19.60 = $22.40 $50.40 (Abdul had at first) - $22.40 (after giving Ben and Chitra) = $28 Ben, 3 x $8.40 + $2.80 = $28 Chitra, 1 x $8.40 + $19.60 = $28 All equal after Abdul gave Ben and Chitra !

For a P3 child is there a simpler way to explain for easy understanding?

Try to find the middle number first. Eg if 1+....100, middle is (50 and 51). So (100+1)×50 =5050 Let say 1+.....7, Middle number will be 4 So (1+7)×3 + 4 =28 Divide the last number you want to add by 2. After dividing if its a whole number, there are 2 middle numbers. If its with 0.5 (eg. 4.5 or 65.5) , there will be 1 middle number.
