A survey of a group’s viewing habits over the last year revealed the following information: (i) 28% watched gymnastics (ii) 29%

almond37 [142]

Answer: D) 52%

Step-by-step explanation:

G = gymnastics

B = baseball

S = soccer

G = 28%

BA = 29%

S = 19%

G and BA = 14%

BA and S = 12%

G and S = 10%

GBS = 8%

So, as we can see at the Venn diagram attached (consider every number in %)

GBS = 8

A = G and S - GBS = 10 - 8 = 2

B = G and BA - GBS = 14 - 8 = 6

C = BA and S - GBS = 12 - 8 = 4

Only G = G - A - B - GBS = 28 - 2 - 6 - 8 = 12

Only BA = BA - B - C - GBS = 29 - 6 - 4 - 8 = 11

Only S = S - A - C - GBS = 19 - 2 - 4 - 8 = 5

So, 2+6+4+12+11+5+8 = 48

100 - 48 = 52%

A bill for Rs 3235 was drawn on Feb. 3, 1998 at 6 months and discounted on March 3, 1998 at 8 % p.a. Find the value of the bill

Fantom [35]

Answer:

RS 3127.166

RS 107.834

Step-by-step explanation:

6 month bill :

Drawn date = Feb, 3

Discounted date = March 3,

Difference = 1 month

6 month - 1 month = 5 months = 5 * 30 = 150 days

Value of the bill :

P(1 - rate * time)

3235(1 - 0.08 * 150/360)

3235(1 - 0.08 * 0.4166666)

3235(1 - 0.0333333)

3235(0.9666666)

= Rs3127.1666

Value of bill = 3127.166

Bankers gain = 3235 - 3127.166 = 107.834

mrs_skeptik [129]

Answer: $75^{\circ}F$

Step-by-step explanation:

Given

If the temperature falls by $8^{\circ}$ in 3 hours

Present temperature is $67^{\circ}F$

The difference in temperature i.e.

$\Rightarrow \text{Previous Temperature}-\text{Present temperature}=8\\\Rightarrow \text{Previous Temperature}=8+67=75^{\circ}F$

Temperature 3 hours ago is $75^{\circ}F$
