As given, Gregory is an American photojournalist in Turkey. He makes a purchase for 32 Turkish lira.
The conversion rate on that day is given as :
1 USD = 1.60 Turkish Lira
or
1.60 Turkish Lira = 1 USD
So, we have to find the value of 32 Turkish Lira in USD. Let us assume that we have to find the value in USD using the same conversion rate.
32 TL = =20
Hence, 32 Lira = 20.00 USD
Answer:
<u>The</u><u> </u><u>requ</u><u>ired</u><u> </u><u>num</u><u>ber</u><u> is</u><u> </u><u>7</u><u>0</u><u>.</u>
Step-by-step explanation:
let the no. be 10y + x where x is unit digit and y is ten's digit.
given , sum of the digit is 7
x + y = 7 ...(1)
also , reversing the no. we get 10x + y ,where x is ten's digit and y is unit digit.
given reversed digit decreases the number by 63 .
so, 10y + x - ( 10x + y ) = 63
9y -9x = 63
( dividing both side by 9 )
y - x = 7 ....(2)
adding 1 and 2 [ refer attachment ]
so the required original number is
10y + x = 10×7+0 = 70
