Answer 1

Sum of 6 numbers =60×30=180

Sum of 6 numbers =60×30=180Sum of first 4 numbers =4×25=100

Sum of 6 numbers =60×30=180Sum of first 4 numbers =4×25=100Sum of last 3 numbers =3×35=105

Sum of 6 numbers =60×30=180Sum of first 4 numbers =4×25=100Sum of last 3 numbers =3×35=105∴ Fourth number =(100+105)−180

Sum of 6 numbers =60×30=180Sum of first 4 numbers =4×25=100Sum of last 3 numbers =3×35=105∴ Fourth number =(100+105)−180 =205−180

Sum of 6 numbers =60×30=180Sum of first 4 numbers =4×25=100Sum of last 3 numbers =3×35=105∴ Fourth number =(100+105)−180 =205−180 =25
