Answer: (e)

Amount received by each son = Rs. 48000

∴ Amount received by her daughter = Rs. 24000 and amount received by the wife = Rs. 96000

∴ Total amount distributed by Shri Ramlal

= Rs. (96000 + 2 × 48000 + 24000) = Rs. 216000

Answer: (d)

Answer: (d)

According to the question,

46x + 30 + 41x + 30 + 34x + 25 = 2505

⇒121x = 2505 – 85 = 2420⇒x= ${2420}/{121}$ = 20

∴ Number of coins received by Parat

= 41x + 30 = 41 × 20 + 30 = 850

Answer: (a)

2m = 5b

2w = 3b

Combining the two relations : (Follow the rule)

2m = 5b

3b = 2w

2 × 3m = 5 × 3b = 5 × 2w⇒6m = 15b = 10w

Now, to find the ratio of wages of a man, a woman and a boy,

let 6m = 15b = 10 w = k (say)

∴ m = ${k/6}; b = k/{15};w = k/{10}$

∴ m : w : b = $1/6 : 1/10 : 1/15$ = 5 : 3 : 2

The ratio of wages of 6 men, 12 women and 17 boys

= 6 × 5 : 12 × 3 : 17 × 2 = 30 : 36 : 34

∴ 17 boys get $50/{30 + 36 + 34}$ × 34 = Rs. 17

∴ 1 boy gets Rs. 1

Answer: (b)

Let numbers be 3x, 4x, 5x

∴$(3x)^2 + (4x)^2 + (5x)^2$ = 1250

$9x^2 + 16x^2 + 25x^2$ = 1250

$50x^2$ = 1250

$x^2$ = 25

x = 5

∴Numbers are = 15, 20, 25

Sum = 15 + 20 + 25 = 60
