Exercise 83:

Solution 1:

• In Marathi, Govinda scored 65 marks in the first term examination and 70 marks in the second term examination.
• Govinda’s marks fell in Hindi and Science in the second term exam.
• Maths marks in the 1^st term = 80

Maths marks in the 2^nd term = 85
Thus, increase in Maths marks in the second term = 85 – 80 = 5

• Govinda’s marks in Maths were more than 80 in the second term.

Solution 2:

• The number of literate women is the greatest in village C.
• The numbers of literate and illiterate women are the same in village B.
• The number of illiterate women in village C is 400.
• Number of literate women in village D = 500

Number of illiterate women in village D = 700
Thus, in village D, the number of illiterate women – number of literate women = 700 – 500 = 200
Hence, in village D, the number of illiterate women exceeds the number of literate women by 200.

•  The number of literate women is the least in village D.

Solution 3:

1. School No. 3 planted the same number of trees every year.
2. School No. 2 planted more trees in 2007-08 than in 2006-07.
3. School No. 1 planted more trees in 2006-07 than in 2007-08.

Solution 4:

• The number of people getting the benefit of the EGS in village R

= Number of men getting the benefit in village R + Number of women getting the benefit in village R
= 170 + 50
= 220

• Village Q has the most women beneficiaries.
• In village S, there are 80 men beneficiaries and 120 women beneficiaries
• Village P has more men beneficiaries.

Solution 5:

• Nikhil’s and Sagar’s scores were same in match II.
• Sagar scored more in match III.
• Number of runs Nikhil scored more than Sagar in the first match

= Number of runs scored by Nikhil in the first match – Number of runs scored by Sagar in the first                  match
= 35 – 25
= 10 runs

• In match II and match IV, Sagar had equal scores.
• In match II and match III, Nikhil had equal scores.
