Let the four whole numbers x, y, z, p. According to the statement,x+y+z=180 y+z+p=197 x+z+p=208 x+y+p=222 Adding these equations, we get, 3x+3y+3z+3p=807 x+y+z+p=269 ......(i) Now put x+y+z=180 in equation ......(i) 180+p=269 p=269−180=89 Put y + z + p = 197 in equation ......(i) x+197=269 x=269−197 x=72 Put x+z+p=208 in equation .......(i) y+208=269 y=269−208 y=61 Put x, y, p in equation .......(i) 72+61+89+z=269 z=269−222 z=47 The largest whole number is 89.
