1/2 + 1/6 + 1/12 + 1/20 + 1/30 + 1/42 + 1/56 + 1/72 + 1/90 + 1/110 + 1/132

= (1 – 1/2) + (1/2 – 1/3) + (1/3 – 1/4) + (1/4 – 1/5) + (1/5 – 1/6) + (1/6 – 1/7) + (1/7 – 1/8) + (1/8 – 1/9) + (1/9 – 1/10) + (1/10 – 1/11) + (1/11 – 1/12)

= 1 – 1/2 + 1/2 – 1/3 + 1/3 – 1/4 + 1/4 – 1/5 + 1/5 – 1/6 + 1/6 – 1/7 + 1/7 – 1/8 + 1/8 – 1/9 + 1/9 – 1/10 + 1/10 – 1/11 + 1/11 – 1/12

= 1 – 1/12

= 12/12 – 1/12

= 11/12

• -1 1/2 + 1/6 + 1/12 + 1/20 + 1/30 + 1/42 + 1/56 + 1/72 + 1/90 + 1/110 + 1/132

= (1 – 1/2) + (1/2 – 1/3) + (1/3 – 1/4) + (1/4 – 1/5) + (1/5 – 1/6) + (1/6 – 1/7) + (1/7 – 1/8) + (1/8 – 1/9) + (1/9 – 1/10) + (1/10 – 1/11) + (1/11 – 1/12)

= 1 – 1/2 + 1/2 – 1/3 + 1/3 – 1/4 + 1/4 – 1/5 + 1/5 – 1/6 + 1/6 – 1/7 + 1/7 – 1/8 + 1/8 – 1/9 + 1/9 – 1/10 + 1/10 – 1/11 + 1/11 – 1/12

= 1 – 1/12

= 12/12 – 1/12

= 11/12

therefore the answer is option B)11/12

I don’t know answer this question

• 0 Shivam Kumar • 0 Jyotsana Shree ☆☆

Antibodies (also known as Immunoglobulins) are proteins. They bind to any foreign organisms like viruses, bacteria, and fungus and further stimulate our immune system to release toxins that may kill these organisms. These are released by B- lymphocytes of the human body.?

An antibody is a Y-shaped structure comprising four polypeptides i.e. two heavy chains and two light chains. The structure is such so as to allow the antibodies to perform their dual functions of?antigen binding and mediation of biological activity.?
