Ans is 3 , 44 , 19

In 1st que. after replacement que. is 25/3*32%5+2 = 8*32%5+2 = 256%5+2 = 1+2 = 3
In 2nd replacement que. is 35/2*4%3+42 = 44
In 3rd is 25*4/5+6-7 = 19

While solving this type of question remember always solve bracket first then /,*,% this thing everybody knows but important thing is these three operations always solve frm left to right always & +,- is always from right to left.

25-3+32/5%2
25/3*32%5+2 = 18.66
35-2+4/3%42
35/2*4%3+42 = 31.5
25+4-5%6*7
25*4/5+6-7 = 19
