Answer»

Actual weight of 45 kids

= 45 x 33 + 27 - 38

= 1485 - 11 = 1474 kg.

REQUIRED actual average weight of those 45 kids

= 1474/45= 32.76 kg.

Quicker Approach

Decrease in weight = 38 - 27 = 11 kg

∴ Required actual average weight

$( = \left( {33\;-\;\frac{{11}}{{45}}} \right) = \;32.76\;kg)$
