What will come in place of the question mark (?) in the following questions?(You are not expected to calculate exact values)
(1610.678 + 2112.897 – 924.343) ÷ 4.453 × 2.344 = ? + 98.888
Verify mobile number to view the solution
(1611 + 2113 – 924) ÷ 4 × 2 = ? + 99 700 x 2 = ? + 99 1400 = ? + 99 ? = 1301≈1300
√1366 + √1761 × 2.786 ÷ 20.889 = ?3 + 15.432
(15.443)2 + (8.678)3 − (11.432)2 = ? + 112.345
(15)2 + (9)3 − (11)2 = ? + 112 225 + 729 − 121 = ? + 112 ? = 721 ≈ 725
90.444% of 899 – ?2 – 19.987% of 400.435 = 419.866 – 11.236 - 352.876
90.444% of 899 – ?2 – 19.987% of 400.435 = 419.866 – 11.236 - 352.876 90% x 900 - ?2 - 20% x 400 = 420 – 11 - 353 810 - ?2 - 80 = 56 ?2 = 674 ? ≈ 26
(19.677 × 18.443) ÷ (15.766 × 15.411) + 16.44 + 2.22 × 1.60 = ?
(20 × 18) ÷ (16 × 15) + 16 + 2 × 2 = ? 360 ÷ 240 + 16 + 4 = ? ? = 1.5 + 16 + 4 ? = 21.5 ≈ 22
The questions given below contain two statements giving certain data. You have to decide whether the data given in the statements are sufficient for answering the question. Read both statements and give answer- (A) If statement I alone is sufficient but statement II alone is not sufficient. (B) If statement II alone is sufficient but statement I alone is not sufficient (C) If each statement alone (either I or II) is sufficient (D) If statement I and II together are not sufficient (E) If both statement together are sufficient but neither statement alone is sufficient.
What will be the rate of interest as the compound interest on a sum of Rs. 8000 is Rs. 2648.
I. Compound interest is compounded every three months.
II. The simple interest on the same sum at the same rate is Rs. 2400.
To find the rate, we need time which is not given. So we cant answer the question.
Find the M.P of a bed.
I. Price of bed is marked 48% more than the C.P and profit earned is 400 Rs. after some discount.
II. 2 beds are purchased for 4400 Rs. and profit earned is 110 Rs. per bed after 46% discount.
From Statement I: Let the C.P = x Rs. M.P = x × 148% = 1.48x S.P = x + 400 Statement I is not sufficient to answer the question. From Statement II: C.P of a bed = 2200 Rs. S.P = 2200 + 110 = 2310 Rs.
Statement II is sufficient to answer the question.
Sumit’s present age is-
I. Varsha is 2 year older than Sumit and the present age of Amita is 40 years.
II. Sumit is 8 years younger than Amita. The ratio of the age of Amita and Varsha is 5 : 6.
From Statement I: Amita = 40 years, Sumit = y, Varsha = y + 2 From Statement II: Let Amita = 5x, Varsha = 6x Sumit = 5x + 8 From both of them- Amita= 40 years, Varsha = 40 / 5x × 6x = 48 years Sumit = 48 – 2 = 46 years Statement I and II both are necessary to answer the question.
Area of the square is-
I. side of the square is 30% more than the length of the rectangle which is x.
II. Perimeter of the square is 76 cm.
From statement II- 4 × side = 76 side = 19 cm Area of the square = 192 = 361cm2 Statement II is alone sufficient to answer the question.
Amount invested by Rakesh in the shop-
I. Simran and Sharda invested Rs 36000 and Rs 44000 Respectively.
II. Total profit earned by three partners Rakesh, Simran and Sharda is Rs 34200.
Statement I: Simran's investment =Rs 36000 Sharda's investment =Rs 44000 Statement II: Total profit =Rs 34200 Statement I and II both are not sufficient to give the answer.
