Answer 1

Answer:

Step-by-step explanation:

Suppose there are 5 rooms name as R1, R2, R3, R4 and R5;

We have to pick 1 bag from R1, 2Bags from R2, 3Bags from R3 , 4 Bags from R4 and 5 bags from R5 room.

Total no. of bags we picked = 1+2+3+4+5 = 15 Bags;

According to the conditions each bag has 100kg so 1500kg is expected weight.

But there is one condition that said one room has 99kg bags;

so that we have to find the difference of 1500- total 15 bags weight;

If it is 2 kg it means R2 has 99kg bags;

If the difference is 3 kg it means R3 has 99 kg bags;

so on
