Solution D1 approach Comment 2 of 2 |

I saw SH's solution- nice and effective . .

However, mine 1is D1 or less- let me share it with you.

he computation basically boils down to dealing with the same numbers, but I treated it as a D1 probloem (no algebra notation , no pen and paper), reasoning as follows:

If Marys age were 0 then G=33(eq1) and S=72(eq2),jointly 105-

now, eq5 specifies only 73, the missing part is twice M's age.

M=32/2=16 & the rest follows  ==>eq4==>eq2.
