Que. 41 If '+' means 'x', '-' means '+', 'x' means '÷' and '÷' means '-', then choose the correct expression from thefollowing options.

Correct Option - 3Symbol + - × ÷

Meaning × + ÷ -

Option 1:14 ÷ 7 - 2 + 48 × 16= 2 - 2 + 768= 768Option 2:38 - 2 × 1 ÷ 6 + 6= 38 - 0.33 + 6= 43.67Option 3:21 ÷ 7 - 7 × 3 + 21= 3 – 21 + 21= 3Option 4:9 ÷ 3 - 12 × 5 + 24 = 3 - 60 + 24= -33Hence, option 3 is the correct answer.

14 × 7 ÷ 2 – 48 + 16 = 971.38 ÷ 2 + 1 × 6 - 6 = 182.21 × 7 ÷ 7 + 3 - 21 = 33.9 × 3 ÷ 12 + 5 - 24 = 314.

Que. 42 For a standard clock, what is the angle between hour hand and the minute hand when the clock shows8:15?

Correct Option - 4The angle between the hour hand and the minute hand when the clock shows 8:15 can be calculated by using thefollowing formula:Angle =

Where M = Minutes and H = HoursHere M = 15 and H = 8

67.5˚1.87.5˚2.127.5˚3.157.5˚4.

× M − 30 × H112

(23)

Therefore, we get angle = = |82.5 – 240| = 157.5˚

Hence, 157.5˚ is the correct answer.

| × 15 − 30 × 8|112

Que. 44 In a class of 60 students, the ratio of the number of girls to that of the number of boys is 2 : 1. A boy isranked 17th in the class, only 9 girls are having ranks ahead of him. How many girls are having lower

ranks compared to that boy?

Correct Option - 1The ratio of the number of girls to that of the boys = 2 : 1.Total number of students = 60Therefore, taking x as the common multiple, we get 2x + x = 60.⇒ x = 20 and 2x = 40.Thus, the number of girls in the class = 40.As the number of girls ranked ahead of the boy who ranked 17th is 9, the ranks of the remaining girls mustbe below 17. Number of girls remaining = 40 - 9 = 31.Hence, 31 girls are ranked lower than the boy who ranked 17th.
