A) 20 years | B) 22 years |

C) 25 years | D) 27 years |

Explanation:

Let Varun's age today = x years.

Then, Varun's age after 1 year = (x + 1) years.

Therefore x + 1 = 2 (x - 12) x + 1 = 2x - 24 x = 25.

A) 27 | B) 13 |

C) 17 | D) 21 |

Explanation:

Let number of bangles kushi purchase of each type = x

From the given data,

34x + 42x + 6x = 1722

x = 1722/82 = 21.

A) 933 | B) 872 |

C) 749 | D) 653 |

**Largest number = 974**

Therefore, the required number is **749.**

A) 1 | B) 2 |

C) 3 | D) 4 |

Explanation:

Given two lines are parallel

pa+b=2

b=-pa+2..........(1)

3a+b=4

b=-3a+4 ...........(2)

m_{1} = -p

m_{2}= -3

The condition for the two lines to be parallel is **m _{1}=m_{2}**

p = 3

A) 0 | B) 1 |

C) 2 | D) 3 |

A) 110 | B) 90 |

C) 100 | D) 180 |

Explanation:

Let number of 2 wheelers be 'x'

and 4 wheelers be 'y'

Given total number of vehicles = 200

i.e, x + y = 200 ....(1)

Given total number of wheels = 580

i.e, 2x + 4y = 580 ...(2)

By solving (1)&(2), we get

y = 90

=> x = 110

Therefore, number of two wheelers = 110

number of four wheelers = 90
