SOF , please explain how the ans is option C . According to my extra ordinary brain , the ans should be option D because 141: 392 { option C } , in this the HCF of 141 and 392 is 1 , so they are co prime numbers. And 153 : 408 { option D} , in this , if we divide by 51 , we get 3 : 8 , so this must be the correct ans. SOF , please correct it .
