Answer : 1. "26"
Explanation :

Answer: A) 26 Explanation: Gold coins = 18000 , Silver coins = 9600 , Bronze coins = 3600 Find a number which exactly divide all these numbers  That is HCF of 18000, 9600& 3600  All the value has 00 at end so the factor will also have 00. HCF for 180, 96 & 36.   Factors of   180 = 3 x 3 x 5 x 2 x 2 96 = 2 x 2 x 2 x 2 x 2 x 3  36 = 2 x 2 x 3 x 3  Common factors are 2x2×3=12  Therefore, Actual HCF is 1200      Gold Coins 18000/1200 will be in 15 rooms Silver Coins 9600/1200 will be in 8 rooms Bronze Coins 3600/1200 will be in 3 rooms Total rooms will be (15+8+3)  =  26 rooms.
