A building with height D shadow up to G. What is the height of a neighboring building with a shadow of C feet?

Read Solution (Total 6)

the sunrays fall on the building in an angle z (say)
So, tan(z)= G/D
Now, for the neighboring building, though it has height C(different than first) yet the angle would be same, because compairing to Sun it is negligible.

So, the original height is, tan(z)= C/x. (say x is the height of the building)
So, the height is DC/G (ans)

as the shadow of the building is 3 feet more than the building just as the height D+ 3=SHADOW =G.similarly the shadow is given C ,hence the height =C-3.hence the height is Z.

when the height of building=d
then shadow =g
so the shadow of building=c
then height of building=z.
becoz the height of shadow is the third letter to the height of building.

this problem is related to similar triangle.Let the height of neighbouring building be x. Therefore D/X=G/C. So x=CD/G

A shopkeeper is preparing a single shipment of candies to be packed in boxes S and N. In each box the shopkeeper will pack three of seven packages of candy: fudge, marsh mellow, chewing gum, peppermints, lollypops, sourballs and toffee. The boxes must be packed according to the following directions: The fudge must be included in the shipment and they must be packed in box S. The marsh mellow must be included in the shipment and they must be packed in box N. The sourballs can neither be packed in the same box as the marsh mellow nor in the same box as the peppermints. The chewing gum and the toffee must be included in the shipment and must be packed together in one box. If toffee is packed in box S, which of the following pairs of candy packages can be packed in box N?
