Explanation

Max marks each subject = 100, so total max = 100 + 100 + 100 = 300

Marks scored = 60% of 100 + 70% of 100 + 80% of 100  

= 60 + 70 + 80 = 210

Overall percentage = 210/300 × 100 = 70%

Explanation

Total balls = 4 red + 5 blue + 6 green = 15 balls

Ways to draw 2 balls from 15 = C(15,2) = 15×14/2 = 105  

Ways to draw 2 green from 6 = C(6,2) = 6×5/2 = 15

Probability both green = 15/105 = 1/7

Explanation

For an A.P., nth term = a + (n-1)d, where a = first term, d = common difference

Given:  

a5 = a + 4d = 18  

a15 = a + 14d = 58  

Subtract: 10d = 40 → d = 4  

Put d=4 in a + 4d = 18 → a + 16 = 18 → a = 2

Sum of first n terms = n/2 [2a + (n-1)d]  

S25 = 25/2 [2×2 + 24×4]  

= 25/2 [4 + 96]  

= 25/2 × 100 = 25 × 50 = 1250

Explanation

Let salary = Rs. S

Total spent = 1/3 + 1/5 + 1/6  

LCM of 3,5,6 = 30  

= 10/30 + 6/30 + 5/30 = 21/30 = 7/10

Money left = 1 - 7/10 = 3/10 of salary

3/10 × S = 600  

S = 600 × 10/3 = Rs. 2000

Explanation

Sum of angles in a triangle = 180°  

Ratio = 2 : 3 : 4 → total parts = 2 + 3 + 4 = 9

Smallest angle = 2/9 × 180° = 40°  

Other angles = 3/9 × 180° = 60°, 4/9 × 180° = 80°

Explanation

When diagonals intersect at right angles, area of parallelogram = ½ × d1 × d2

Here d1 = 12 cm, d2 = 16 cm  

Area = ½ × 12 × 16 = 6 × 16 = 96 cm²
