Let x be the price of a tie in dollars.
Then, the price of a watch is 11/4 times the price of a tie, or (11/4)x dollars.
Mr Raju paid $69 for a watch and 3 ties, so we can write an equation:
(11/4)x + 3x = 69
Simplifying the left side:
(11/4)x + (12/4)x = (23/4)x
Combining like terms:
(23/4)x = 69
Multiplying both sides by 4/23:
x = 12
Therefore, the cost of a tie is $12.
To find the cost of a watch, we can use the expression we found earlier:
(11/4)x = (11/4)($12) = $33/2 = $16.50
So the cost of a watch is $16.50.
Mr Raju paid $69 for a watch and 3 ties. The price of a watch was 11/4 of the price of a tie.
