## Question 4

### Question

MCQ▾The temperature in first three days of the week is 27 and the next three days is 29 and the average temperature of the week is 28.5. What is last day՚s temperature?

### Choices

Choice (4) | |
---|---|

a. | 27.5 |

b. | 42 |

c. | 31.5 |

d. | 41.5 |

### Answer

c.### Explanation

There are total 7 days in a week.

For first three days the average temperature is 27 and for next three days average temperature is 29.

The average temperature of whole week is 28.5.

Total temperature of first three days =

Total temperature of next three days =

Total temperature of whole week =

We can get the last day՚s temperature by subtracting the total temperature of first six days from total temperature of whole week.

Let the temperature of last day be x.

Then,

So, temperature of the last day is 31.5

## Question 5

### Question

MCQ▾In a triangle (B + C) = 130 find A if Angle A = Angle C.

### Choices

Choice (4) | |
---|---|

a. | 60 |

b. | 70 |

c. | 80 |

d. | 50 |

### Answer

d.### Explanation

Let, measure of angle A and C be x.

So, measure of … (i)

The sum of measurement of all the angles of triangle is 180.

So, x + x + measure of B = 180

So, measure of … (ii)

Solving both the equations,

x = 50 i.e.. measure of A = measure of C = 50

Measure of angle b will be 80
