1. 1

He sells 920 grams of rice and gains 80 grams

Gain % = 80/920 * 100 = 8.69%

1. 2

Let the number of days he was absent be x days.

180 (40 – x) – 20 x = 5200

7200 – 180x – 20x = 5200

7200 – 200x = 5200

x = 2000/20 = 10 days

1. 2

Required number = LCM of (25, 30, 35, 40) – 7

= 4200 – 7 = 4193

1. 3

Time stopage rest per hour

Difference of speed/ Speed without stoppage = 60 minute

Now, 54-36/36 * 60 = 30 min per hour

1. 5

Let Manorama son’s age be x years

Manorama’s age = 6x

(6x + 7)/(x + 7) = 11/3

18x + 21 = 11x + 77

7x = 56

x = 8

Manorama’s present age = 6x = 48 years

1. 4;

Amount of salt in 40 kg of solution = 4/100 * 40 = 1.6 kg

Let x kg of pure salt be added.

Then, (1.6 + x)/ (40 + x) = 12/100

160 + 100x = 480 + 12x

88x = 320

x = 3.64 kg

1. 3

(80x + 94y)/(x + y) = 86

80x + 94y = 86x + 86y

8y = 6x

x/y = 8/6 = 4/3 = 4 : 3

1. 1;

Radius of formed cone = 4 cm

Slant height = 5 cm

Surface area of formed cone = πrl = 22/7 * 4 * 5 = 62.8 cm^2

1. 1

N2 – 35% of N1 = 4/5 N2

N2 – 4/5N2 = 35/100N1

N2/5 = 35/100N1

N1/N2 = 1/5 * 100/35 = 4 : 7

1. 2

Let the age of Anshu be x years

Bharti’s age = 3x

Charita’s age = x + 12

x + 3x + x + 12 = 57

or, 5x + 12 = 57

x = 9

Anshu, Bharti and Charita’s age are 9, 27, 21 years
