Answer:
48
Step-by-step explanation:
48
Let the tens digit be x.
Hence, the units digit will be 2x
Number =10×(x)+(2x)=12x
When 36 is added to the number, the new number formed =12x+36
As the digits are reversed, we can also write the new number as 10×(2x)+x=21x
Hence,
12x+36=10×(2x)+x
⇒12x+36=21x
⇒21x−12x=36
⇒9x=36
⇒x=4
Hence, the original number =12x=12×4=48

Answer:
5x3-6x2-4x+7...(a)
Step-by-step explanation:
(5x3-12x+4)+ (6x2-4x+3)
15-12x+4+12-4x+3
5x3-6x2-4x+7
No of coins Sparrow had in the beginning 92 coins
Step-by-step explanation:
Total coins = 210
Current ratio = 4:5:6
It implies 210 needs to be split into 15 parts (4+5+6)
So, each part = 210/15 = 14 coins
Again which implies 14*4 : 14*5 : 14*6 = 56 : 70 : 84
So before the game began,
No of coins Ahab had = (56 - 5) = 51
No of coins Davy had = (84 - 7) = 67
Hence, No of coins Sparrow had = (210 - 51 - 67) = 92 coins
