**Answers With**

Explanation:-

Explanation:-

**1. (4)**

Average Speed = (2 * 40 * 50)/90 = 44.444 km/hr

**2. (4)**

Required price = 39 * 1.1/1.3 = 33

**3. (1)**

Let the numbers be 2x and 3x.

6×2 = 54

x = 3

Sum of numbers = 5x = 15

**4. (4)**

Let the total number of pages be x.

x – x/3 – x/6 = 75

x = 150

**5. (1)**

P can finish the job in = 3/2 of 8 = 12 days

SO Q will take 12/2 = 6 days to finish the job.

**6. (4)**

Daily wages are in the ratio 3 : 4 : 5 ,

working days of A,B,C = 8,9 and 12 so the wages they get will be in ratio 24 :

45 : 48,

Share of C = 48/(24+45+48) × 1950 = Rs 800

**7. (2)**

chain rule ; if 100 men will do one job in 100 days individually , so one man

will do one job in 100 days .

**8. (4)**

C.P. of one mango = 12/15 = 80 paise ; S.P. of

one mango = 15/12=Rs 1.25 ;

Gain = 45 paise , gain = 45/80 × 100 = 56.25 %

9. (1)

average

speed = (2x×y )/((x+y))=(2 × 50 × 60)/(50 + 60) = 600/11 = 54 6/11 km/hr

**10. (2)**

value of (90% – 83%)x = 175, 7% of x = 175, 100

% = 2500

99 % of 2500 = 2475

Thank u soooo much

Mam

Math me questions ka std aur upar kare please

Okk…..

8/10..

Not getting question no. 8.

anyone explain 6th question

9/10

Daily wages are in the ratio 3 : 5 : 4 ,

working days of A,B,C = 8,9 and 12

so the wages they get will be in ratio

(3*8):(5*9):(4*12)

=24 : 45 : 48

=8:15:16,

Share of C =1950*16/(8+15+16)

=1950*16/39

= Rs 800

Thanks Kaushik.

A fruit seller buys mangoes at the rate of 12 for 15 and sells them

at the rate of 15 per dozen. Find his gain percentage.

ANS: cp(15 mangoes)=12 rupees

sp(12 mangoes)=15 rupees

after making eqal mangoes

cp of 60 mangoes =48 rs

sp of 60 mangoes =75 rs

p%= (75-48)/48 *100 =56.25
