a. 8:35

b. 25:52

c. 35:8

d. 52:25

**Answer:** b. 25:52

**Explanation:**

Children's drink → Juice : Water = 5:2 → Total 5+2 = 7 parts of liquid

Adult's drink → Juice : Water = 7:4 → Total 7+4 = 11 parts of liquid

Jug juice = Juice from children's mix + Juice from adult's mix = | 5 | + | 7 | = | 104 |

7 | 11 | 77 |

Jug Water = Water from children's mix + Water from adult's mix = | 2 | + | 4 | = | 50 |

7 | 11 | 77 |

Water to Juice ratio in Jug = | 50 | : | 104 | = 25:52 |

77 | 77 |

a. 24 litres

b. 36 litres

c. 48 litres

d. 50 litres

**Answer:** c. 48 litres

**Explanation:**

Let Oil B quantity be B litres.

Final mixture has '60+B' litres

There is no profit no loss

So, (Oil 1 quantity * rate) + (Oil 2 quantity * rate) = Mix quantity * rate

Oil B is 9 Rs/- cheap. So, the rate of Oil B per litre = 23 Rs/litre

∴ 60 x 32 + B x 23 = (60+B) x 28

**∴ B = 48 litres = Oil B quantity**

a. 20L

b. 40L

c. 90L

d. 100L

**Answer:** c. 90L

**Explanation:**

3 vessels of 30 litres each = 3 X 30 = 90 ml milk mixture

Amount of milk in mixture = | 2 | x 90 = 60L |

2+1 |

To make milk to water ratio 1:2, we simply need to make water double of milk.

By direct observation, we can say that we should have 60L x 2 = 120L water to make the required ratio

We already have 30L,

a. Rs. 196.58

b. Rs. 208.33

c. Rs. 210

d. Rs. 215.67

**Answer:** b. Rs. 208.33

**Explanation:**

Let the rate of 3^{rd} type of wheat be Rs. W

Quantity ratio = 2 : 1 : 3

This means if we take 2kg of Type 1 and 1 kg of Type 2, then we must take 3kg of Type 3.

Also, the mix will have 2kg + 1kg + 3kg = 6 kg quantity.

∴ (145 x 2) + (165 x 1) + (3 x W) = 6 x 180

**∴ W = Rs. 208.33 per kg = 3 ^{rd} type price per kg**

a. 72.9 Litres

b. 75 Litres

c. 80 Litres

d. 81 Litres

**Answer:** b. 75 Litres
