Let Ramesh’s monthly salary be Rs 100

Investment in Chit fund = Rs 30

Expenditure on EMI = (70 *20)/100= Rs 14

Expenditure on food = Rs 24

Expenditure on shopping =Rs 16

Savings = 100-(30+14+24+16) =Rs (100-84)= Rs 16

When saving is Rs 16, monthly salary = Rs 100

When savings is Rs 4800, monthly salary = Rs (100*4800)/16= Rs 30000IncorrectAnswer –

1 pointsCategory: Quantitative Aptitude**A watercraft travels 65 km downstream in 6 hours 30 minutes when it is travelling in a stream (X1). If this watercraft travels in another stream (X2) whose speed is 10% more than that of (X1). It covers 58 km upstream in 10 hours. What is the speed of (X2)?(in kmph)(assume the watercraft’s speed in still water in both streams remains the same)**CorrectAnswer –

**1. 2.2 kmph**

Explanation:

Speed of current (X1) = b kmph

Speed of watercraft in still water = a kmph

Rate downstream = a+b= 65/(13/2) =10kmph

Speed of current (X2)=11b/10 kmph

Rate of upstream = a – 11b/10=5.8 kmph

b = 2 kmph

Speed of current (X2) = (11*2)/10 = 2.2 kmphIncorrectAnswer –

**1. 2.2 kmph**

Explanation:

Speed of current (X1) = b kmph

Speed of watercraft in still water = a kmph

Rate downstream = a+b= 65/(13/2) =10kmph

Speed of current (X2)=11b/10 kmph

Rate of upstream = a – 11b/10=5.8 kmph

b = 2 kmph

Speed of current (X2) = (11*2)/10 = 2.2 kmph - Question 8 of 10
