बांधकामाच्या भोवतीच्या मलबाच्या सफाईशी संबंधित करारात ठरलेल्या दिवसांत काम पुरे झाले नाही तर विशिष्ट दंडाची तरतूद पुढीलप्रमाणे केलेली आहे. 1 ल्या दिवसासाठी 250 रुपये; 2 व्या दिवसासाठी 310 रुपये; 3 व्या दिवसासाठी 370 रुपये या प्रमाणे. जर ठेकेदाराने 6960 रुपये दंड भरला असेल तर त्याने कामाला केलेल्या विलंबाचे दिवस निवडा.
The penalties form an AP where first term a = 250 and common difference d = 60. Using the sum of AP formula S_n = n/2 * [2a + (n-1)d], we substitute S_n = 6960 to find n = 15, representing the number of delayed days.
प्रश्नचिन्हाच्या (?) जागी कोणती संख्या असेल? [Diagram showing a stack of triangles with numbers: 3, 5, 8, 13, 22, ?] Which number will replace the question mark (?) :
The differences between the numbers are 2, 3, 5, 9, and those differences themselves grow by 1, 2, 4. The next difference is 9 + 8 = 17, so the missing number is 22 + 17 = 39.
खाली एक संख्या मालिका दिलेली आहे. त्यापैकी एक पद चुकीचे आहे. चुकीचे पद दिलेल्या पर्यायामधून निवडा. 3, 10, 29, 60, 127, 218, 345 A number series is given, with one wrong term. Select the wrong term from the given alternatives : 3, 10, 29, 60, 127, 218, 345
The series follows the pattern n³ + 2: 1³+2=3, 2³+2=10, 3³+2=29, 4³+2=66 (given is 60), 5³+2=127, 6³+2=218, 7³+2=345. Thus, 60 is the wrong term.
