Show answer & explanation

Correct answer: C

Explanation

The correct answer is option 3 i.e. 23/20

Given that

52−37×145÷36732+125÷312×114{{5\over2 }- {3\over7} \times 1 {4\over5} \div 3{6\over7}}\over{{3\over2}+1{2\over5}\div3{1\over2}\times1{1\over4}}

= [(5/2) - (3/7) * (9/5)/(27/7)]/[(3/2) + (7/5)/(7/2) * (5/4)]

= [(5/2) - (3/7) *(7/15)]/[(3/2 +(1/2)]

= (5/2) - (1/5)]/2

= 23/20
