Answer : 3. "1400"
Explanation :
Answer: C) 1400 Explanation: Given the ratio of the circumference of front wheel is 40 inches and back wheel is 70 inches Distance covered = Circumference of the wheel × No. of Revolutions made by the wheel If n is the number of revolutions made by back wheel, the number of revolutions made by front wheel is n+15 Distance covered by both the wheels is the same 40*(n+3)=70n n=20 Front wheel : Back Wheel Circumference 40 : 70 Revolutions 35 : 20 Distance covered : 40×35 = 70×20 = 1400 inches.

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.
