Here are the grammatical errors in questions 109 to 115, along with explanations:

109. Everybody, it must be admitted, has their ups and downs.
- Error: "their" (c)
- Explanation: "Everybody" is singular, so it should use a singular pronoun. "His or her" should replace "their."
- Correction: "Everybody, it must be admitted, has his or her ups and downs."

110. When the thief broke into their house, they raised a hue and cry and the thief caught immediately by the people.
- Error: "the thief caught" (c)
- Explanation: The sentence is in active voice, but "caught" is in passive form. It should be "the people immediately caught the thief."
- Correction: "When the thief broke into their house, they raised a hue and cry and the people immediately caught the thief."

111. I have tried to meet him several times; he isn’t never at home.
- Error: "isn’t never" (c)
- Explanation: The double negative ("isn't" and "never") is incorrect. It should be "isn't ever" or "is never."
- Correction: "I have tried to meet him several times; he is never at home."

112. This house is mine.
- Error: No error (d)

113. He is proficient in Hindi and can speak English, but he does not know to read and write English.
- Error: "to read and write" (c)
- Explanation: The verb should be "how to read and write."
- Correction: "He is proficient in Hindi and can speak English, but he does not know how to read and write English."

114. Every woman in the world fervently hopes that their child will be a normal and healthy baby.
- Error: "their" (b)
- Explanation: "Every woman" is singular, so it should use the singular pronoun "her."
- Correction: "Every woman in the world fervently hopes that her child will be a normal and healthy baby."

115. Neither of them send their papers in time for the last seminar.
- Error: "send" (b)
- Explanation: "Neither" is singular, so it should use "sends."
- Correction: "Neither of them sends their papers in time for the last seminar."

Here are the grammatical errors in questions 116 to 120, along with explanations:

116. There is not many traffic along the street where I live.
- Error: "many" (a)
- Explanation: "Traffic" is an uncountable noun, so "much" should be used instead of "many."
- Correction: "There is not much traffic along the street where I live."

117. The front page story was about a schoolgirl, and had hurt herself while saving a child in an accident.
- Error: "and had hurt" (b)
- Explanation: The subject is "the front page story," which cannot "hurt herself." The sentence should be restructured, or the verb needs to be clarified. It could be "who had hurt herself" if referring to the girl.
- Correction: "The front page story was about a schoolgirl, who had hurt herself while saving a child in an accident."

118. He took leave of four days.
- Error: "leave of" (b)

119. The police arrived and discovered a large number of hoarded sugar in his shop.
- Error: "a large number of" (b)
- Explanation: "A large number of" is used with countable nouns, but "sugar" is uncountable. It should be "a large amount of."
- Correction: "The police arrived and discovered a large amount of hoarded sugar in his shop."

120. Raju doesn’t come to our house because our dog barks at him and licks him although I have often told him not to afraid of it.
- Error: "not to afraid" (c)
- Explanation: The correct form is "not to be afraid." "Afraid" is an adjective, so it needs the verb "be."
- Correction: "Raju doesn’t come to our house because our dog barks at him and licks him, although I have often told him not to be afraid of it."
